Sable Replay Compat

Compatibility for the Sable physics engine with ReplayMod (reforgedplaymod): makes moving Sable
SubLevel contraptions correctly recordable and replayable in replays

What it fixes:

• Movement recording. Sable broadcasts SubLevel pose snapshots bypassing the regular Minecraft
  connection (in singleplayer via a direct call, in multiplayer over a separate UDP channel), so
  ReplayMod does not record them and contraptions "freeze" in replays. While recording is active,
  the mod routes the snapshots over the regular channel — so they end up in the replay, and on
  playback the contraptions move again.
• Quick Mode. ReplayMod's quick mode rebuilds the world without NeoForge's modded network
  handshake, which leaves the client stuck forever on the "Reconfiguring" screen. During a replay
  the mod waves the connection through the NeoForge checks as a vanilla connection, and the world
  loads.

Useful for Sable-based mods — for example Create: Aeronautics (flying contraptions) — to record
cinematic replays with moving ships and machines.

Sable, ReplayMod(reforgedplaymod) is required.

Note: only replays RECORDED while this mod is installed and active will show moving contraptions.
Old replays recorded without the mod have no movement data baked in and cannot be fixed afterwards —
contraptions will stay frozen on playback. Record a fresh replay to see the fix.
