This makes the Teleport action functional now, although it looks pretty
rough as it warps you instantly instead of waiting for the action to
actually finish.
Kawari is starting to have more and more Excel-based code, so having a
nicer way to access it is nice. This only works for simple cases for
now, and easy one is finding a warp.
This updates three major crates we use to the latest version with all of
their API changes, and the others too. Notably, this removes the Syn v1
dependency thanks to binrw 0.15 switching to Syn v2.
I seem to have finally restored the reliability back to how it used to
be, it seems the crux of it was the Excel sheet reading for Items. I
moved the parsing to the start-up instead.
Instead of standalone functions in the common module to perform game data tasks,
there is now a shared GameData struct that these functions moved to. This speeds
up a few things, and can take advantage of Physis' built-in index caching.
I know the current solution isn't ideal (each connection has to mutex lock to
access gamedata) but it's at least better than before.
