* Removes scaled speed by dex for monsters
* Changes scaled speed by dex for pets (HS+ expansion) to be 400ms -> 100ms between 50 -> 200 dex
* Removes speed changes that were broken for various mobs
* Combines "Legacy" speed and renames the class to `NPCSpeeds`
* Creates speed "classes" (slow, medium, fast, very fast)
* Introduces a new overridable property `SpeedClass`. Register a new speed class using `NPCSpeeds.Register()` and then set the speed class to bulk/mass apply speeds.
Order of speed determination:
1. SpeedMod
2. SpeedClass property (not null)
3. SpeedClass entry in Data\npc-speeds.json for that type
4. "Fast" (200ms Active, 400ms Passive)
Changes gump compilation to use string interpolation. .NET 6 uses code generation and compile time tricks to speed up string interpolation between 15 and 30% and reduce allocations dramatically.
## Added Feature
Adds a single threaded array pool that works exactly the same as `ArrayPool<T>.Shared`.
The `STArrayPool<T>.Shared` can only be used on a single thread, the main game thread of the server.
Note: Unlike the built-in array pool, there is no hook into the _GC Gen 2_. This means to relieve potentially high memory pressure, `ArrayPool<T>.Shared.Trim()` must be called. The pool will only release arrays _after two successive calls within 10 seconds or longer_. If the server is at less than 70% total memory usage, or the server is not going to use this pool for something egregious, then don't bother ever calling Trim().
## Changes
- [X] Fixes ArrayPool calls that should be cleared due to references.
- [X] Benchmarks against ArrayPool with 4+ rented arrays deep of the same length.
- [x] Unit tests
- [X] Removes static freezing/unfreezing. Use other tools for this.
- [X] Cleans up IPoint3D allocations
- [X] Removes IPoint3D constructors since the compiler may not optimize the constructor path and allow allocations.
Note: Instead of `new Point3D(m)`, do something like `new Point3D(m.Location)`. Sorry for the inconvenience. In the long run this will prevent abuse of hot paths that will cause performance issues.
- [X] Removes several `ToList()` uses with `PooledRefQueue`
- [X] Adds a `PeekRandom` to PooledRefQueue
- [X] Updates EV/BS so they dispel each other in a more efficient manner.
- [X] Fixes Firebomb so it works like a normal firefield.
- [X] Fixes field spells so they aren't unnecessarily using a Point3D ref more than necessary.
- [X] Removes extra allocation in campfire by using reverse loop.
- [X] Removes other LINQ calls that aren't needed.
* Adds the following configurations:
* `movement.delay.npcMinDelay` - 0.1 - Pets or Non-monster NPCs
* `movement.delay.npcMaxDelay` - 0.4 - Pets or Non-monster NPCs
* `movement.delay.monsterMinDelay` - 0.4 - Non-pet Monsters or NPC vs Player Combat
* `movement.delay.monsterMaxDelay` - 0.8 - Non-pet Monsters or NPC vs Player Combat
* `movement.delay.monsterMinDex` - 150 - Dex maximum for delay by dex
* `movement.delay.MinDex` - 190 - Dex maximum for delay by dex
Fixes an issue with DropReq where an old client was sending in 14 bytes, but the server was expecting 15 bytes.
To fix this we introduced a new packet handler, `ContainerGridPacketHandler` and changed the code to determine the length of the packet dynamically using `GetLength(NetState)`.
Also fixed throttling so dropped packets are properly skipped.
