fix(core): Fixes map issues at New Haven (#509)

- [X] Fixes map issues at New Haven by turning off static diffs
- [X] Some code cleanup and reformatting of tile matrix, tile matrix patch, and tile data
- [X] Adds NetState.Flush for generating spawners so it doesn't feel like the server is frozen
- [X] Reverts NativeReader changes from a while back.
- [X] Adds more string reading for BufferReader.


Notes:
BufferReader is still `little endian` compared to `SpanReader` which is `big endian` (for packets). To that end, the RunUO deserialization `ReadString()` was made obsolete since it is ambiguous, and contains extra fields other than simply reading a string. Furthermore, we shouldn't be using UTF8 (for now) since it is slow.
