Perfecting the APU

Description

There are multiple tasks still pending to have a perfect and stable APU component.

• Support for reading APU registers
• Support for the Global registers (both read and write)
• Handling of stereo and global operations (mute, etc)
• Better trigger (initialization of the channels)
• Blargg Audio tests passing - https://github.com/retrio/gb-test-roms/tree/master/dmg_sound (currently only 2 of them)

Previously applied strategy from !26 (merged) it involved:

• Implementing the global audio registers
• Implementing all the read register operations
• Going step by step over the multiple tests
• Reading the source of the tests to control fixing
• Used the 'dmg_sound/rom_singles' files for test-by-test execution
