Better V53 Support + Better V52 Header & Bone

[IJARika]

Fixes the header, bone, and ikchain structs for V53 MDLs. This fixes the following issues: -jointcontents not exporting right -bone flags being broken -jiggle bones actually exporting (see above) -lods writing in qc -bone table by name working -source bone transforms working -linear bone table working -pose parameters working -ikchains actually exporting and writing in qc -physics smds no longer clumping around origin

For V52 only the bone and header struct were adjusted to be more accurate.

There is probably some pretty messy code bits in here but all seems to function at least on my end.

Unrelated but this also makes the $worldalign command work shrug
