* ajm: Initial ajm implementation

* AJM code improvements (shadps4-emu#1453)

* Fix sideband buffer order (shadps4-emu#1454)

* ajm: Attempt to add gapless support

* ajm_at9: Return superframes decoded in a single job

* WIP (shadps4-emu#1460)

* Fix gapless decode and combine split buffers

* Fixed linux build

* fix number of samples reported with gapless decoding

* fixed number of remaining samples calculation

should fix the small crackling sounds that play every now and again

* refactor half ajm

* refactored most of ajm

* refactored ajm

* clang-format, in-repo libatrac9, removed debug stuff
