[sparticle] 2d hud particles (#849)

* wip, taking a break to work on asm stuff first

* the goal code for sparticle

* mips2c the first sparticle asm function

* temp

* particle processing no longer crashing

* temp

* working texture cache for vi1 and hud textures

* sprites

* cleanup 1

* temp

* temp

* add zstd library

* temp

* working

* tests

* include fix

* uncomment

* better decomp of sparticle stuff, part 1

* update references
