Removes empty trashbyte array allocation (less objects)
Change int[] to byte[] (less filesize/mem) (-256*6)
Change int[] to ushort[], precompute reverse table in saved space
removes dictionary lookup for array index fetch (faster, less memory, no
temp obj allocations!)
could make the ushort[] arrays into byte[] by changing them to be value
shifts? Not worth saving filesize for cpu.
reduces loading time (don't have to allocate conversion arrays when
launching a gen7 game), and separates things to easier to manage
locations
reworks gen3 string encode/decode, no longer does 3->4->5 and 5->4->3;
instead goes straight to the end result without an intermediary format.
String sanitization should probably be broken up rather than reused, oh
well.
