Adds support for the Zelda Oracle.

Thsi avoids possible overflow issues.

Also added CH4 public WASM API

The all trigger was missing calls to channel 2 and 4.

This issue was prevent CH4 from working properly.
Also added TODO operations to the master volume.

The implemenation seems correct but is yet to be tested.
The coding of LFSR still needs auditing.

Also fixed small channel 3 issue

Improves performance of APU by an order of maginute at the cost of less accurate emulation.

There's still no control over the channels themselves, but the basic interleaved buffer support is now coded.
There's also new support for buffer size definition in seconds.

Support for set of video, audio and timer.
Now with support for toggling audio in the SDL version.

Using a dequeue it's possible to control the size of the queue and outdate old elements.

Now the BIOS beep works perfectly.

There's some testing pending but audion is getting perfected.

The emulator is now sounding more like a real audio player .

These are temporary fixes.

Silences clippy.

It's stil glitchy and noisy, need to check the problems.

Still requires work to be able to be able to emulate APU together with the CPU instead of inverting the control.

There's still a lot of work needed.
