-288 KB (-31%) across lvlmove/eggmove/evolve binaries redesign the levelup bins: - be moves_levels rather than the "official" -1 stop of the past era. - gen1/2 reformatted from byte,byte[] to ^ to skip initialization work redesign the eggmove bins: - be simply moves[], rather than the "official" -1 stop of the past era; now is just a struct to keep the array readonly with no further allocation. - same for gen2 skipping initialization byte[]->ushort[] - for gen7/8 formtable indexed, just use the personal table indexing style of SV. added a 16-bit version of BinLinkerAccessor as start/end offsets of <65KB files are always 16bit. Saves a fair bit of space in eggmoves/evo where there's often 0 entries for a species-form. Obviously binlinker16 is an unofficial format, but there's no need to replicate official serialization formats if we instead use a universal & maintainable alternative. Plus they don't even use BinLinker across all their games. Adds a debug BinLinkerWriter because I'm tired of digging up the zipping implementation :)
