Earle F. Philhower, III 07500e89db Rewrite I2S from scratch, add I2S input support (#569)
Rewrite the I2S code from scratch to eliminate the dependence on the
pico-extras implementation and to support I2S input as well.

8-bit, 16-bit, 24-bit, and 32-bit words are supported.

Multiple I2S ports are allowed (theoretically up to 6 because
2 DMA channels are required per port).

I2S input and I2S output are supported.

Add input example
