fix(core): Tightens the network stack (#479)
- [X] Removes network pause/resume
- [X] Adds back packet profiler
- [X] Adds state machine to keep track and trace netstates
- [X] Changes NetState.Running back to using an interlock exchange
- [X] Adds preliminary packet throttling support


### Packet Throttling
- `[GetThrottle <packetId>` to get the delay in milliseconds for that packet
- `[SetThrottle <packetId> <delay>` to set the delay in milliseconds for that packet
The settings are saved to `Configuration/throttles.json`

fix(core): Adds SkipLocalsInitAttribute support, optimizes broadcasted packets (#363)
- [X] Adds support for `SkipLocalsInitAttribute`. SkipLocalsInitAttribute skips initializing stack variables including `stackalloc`. I don't think it is wired/working yet but should be implemented soon.
- [X] Optimizes broadcasted packets by checking if the first byte (packet ID) is non-zero. If it is already set, it reuses the buffer.
- [X] Removes unnecessary refs to Spans. I don't think the Span struct itself is mutable, so a ref is not helpful.

fix(core): Optimizes strings / .NET 5 compatibility changes (#354)
- [X] Removes some string allocations (e.g. split)
- [X] Optimizes some collections
- [X] Converts insensitive to extension methods of built-ins.
- [X] Adds ordinal (case sensitive) string helpers
- [X] Fixes conditionals for in-game commands so they use Ordinal comparisons.
- [X] Replaces ToLower.Contains with InsensitiveContains
- [X] Adds ValueStringBuilder
- [X] Implements ValueStringBuilder in a few places where it makes sense
- [X] Removes the redundant Wrap function and replaces it with an optimized version
- [X] Fixes list conversions in Utility

Closes #351

Updates movement packets & Fastwalk (#324)
- [X] Updates Movement packets
- [X] Adds OSI fastwalk packets. These aren't used on OSi anymore.
- [X] Adds new movement handling, but looks like the client doesn't use it. (Also leaving the 0x4000 Character List Flag off)
- [X] Adds time sync request handler, but also looks like the client doesn't use it.
- [X] Adds time sync response for time sync, just in case, but it isn't used, so not sure about the arguments.
- [X] Reimplements RunUO's fastwalk to use a circular array on the netstate instead of every mobile
- [X] Removes ClearFastwalkStack from RunUO implementation. This shouldn't be needed anymore

Changed fastwalk settings:
```cs
        public static int WalkFootDelay { get; set; } = 440;
        public static int RunFootDelay { get; set; } = 220;
        public static int WalkMountDelay { get; set; } = 220;
        public static int RunMountDelay { get; set; } = 110;

        public static bool EnableFastwalkPrevention { get; set; } = true;
        public static AccessLevel FastwalkExemptionLevel { get; set; } = AccessLevel.Counselor;

        // If this is changed during runtime, then the steps array needs resizing.
        public static int MaxSteps { get; private set; } = 4;
```

modernuo.json
```json
{
  "settings": {
    "movement.delay.runFoot": "220",
    "movement.delay.runMount": "110",
    "movement.delay.walkFoot": "440",
    "movement.delay.walkMount": "220",
    "movement.enableFastWalkPrevention": "True",
    "movement.fastwalkExemptionLevel": "Counselor",
    "movement.maxSteps": "4"
  }
}
```

Notes about OSI fastwalk:
While it does work, I can't find a benefit in using it because of the variable speeds. If players moved at a single speed then we could refill the stack every X milliseconds with 6 keys and use a naive token bucket implementation.
Unfortunately variable speeds mount/run/walk/etc means we would have to use a leaky bucket algorithm.
If we are using a leaky bucket algorithm with a variable leak, then we don't need to send tokens because we are already tracking it on the server side.

ModernUO vs OSI Fastwalk:
When the fastwalk was implemented on OSI, it used up to 6 tokens. These tokens were probably distributed every 600-750 milliseconds. To get the same effect, the new fastwalk settings might need to be adjusted. I would tweak them and feel free to let me know what worked for you!

Fixes bugs in world save (#297)
- [X] Fixes bugs in the buffer writer
- [X] Removes background save commands
- [X] Avoids calling Serialize() on deserialization
    - In a future optimization I will copy the entire object to a buffer, deserialize using a SpanReader, then use that buffer for the SaveBuffer
- [X] Fixes issue with decay queue.
