fb46a44e18 Begin correctly implementing packet obsfucation
I re-implemented Unscrambler, but in reverse! This currently only
affects names in the PlayerSpawn packet, it needs to be extended
into others to be considered complete.

See #9

6ecdae840c Continue parsing when encountering unknown packets
This reads the unknown packet data, just throwing it in a byte
buffer. This allows us to read the rest of the segmenets in
the packet, and fixes parsing.

Note that this still log spams with "wrong size" as we can't
determine the size of the unknown packet ahead of time. This is
easy to fix, but it's not a high priority yet.

Fixes #73

db3166d8b3 Add various things useful for using Kawari downstream
Such as better unknown packet parsing, IPC opcode names and
more stuff exposed as public API.

d11c6ad090 Restore and add the remaining 7.2 opcodes
Now Kawari is back to it's full functionality, save for tests being
broken and out of date and PlayerSetup has the wrong padding. Success!

3a66e4466c More various 7.2 packet fixes, attempt to check recieved packet size 2025-03-26 19:23:14 -04:00
dae20a1e0c Rename IpcSegmentTrait to ReadWriteIpcSegment, add docs
This also adds a default calc_size() implementation so client packets don't have
to implement it.

7315ece194 Move some larger Lobby IPC structs to their own files, add more tests for these
Also fix a bunch of mistakes when calculating size, and so on.

f5d75301b2 Re-organize the IPC structures so they live in their own server-specific module
My old setup of throwing *all* of the IPC types and opcodes into *one* enum was
becoming unbearable. Now that we have multiple things using the same opcodes
(because they can overlap) I think it's time to repay this technical debt.

This overhauls the structure of the project to move IPC structs into their own
modules, and separate the opcode data/lists into separate ones depending on if
it's clientbound and serverbound.

Nothing has changed functionall, but this is going to make it way easier to add
more IPC in the future.
