[Audio 8/?] Check-in handwritten sequences, build sequences, automate various sfx arrays (#2137)
* [Audio 8/?] Check-in handwritten sequences, build sequences, automate various sfx arrays

* Fix whitespace in aseq.h

* Fix sequence 0 sfx id generator

* Suggested changes, adjust some MML syntax and add more instruction descriptions

* Correct some formatting in aseq.h

* Add the dir of the input .seq file to the list of includes to sequence assembling so that assembler-level includes like .include or .incbin work intuitively

* aseq.h tweaks

* MM review suggestions, aseq.h adjustments
