v1.0.2

This release fixes some issues with the bidi slave and removes hardcoded pio0 typos left over in the helper routines.

Thanks to @murdo-g and @alefais for their help identifying these issues and submitting fixes.

v1.0.1

Minor update to use signed integers for buffer contents to reflect standard I2S formatting.

v1.0.0

Version 1.0.0 of rp2040_i2s_example.

Contains the core I2S PIO and supporting i2s.h/i2s.c code to set up DMA double buffering and clocks properly, along with i2s_example.c with a fully working (but basic) audio processor setup, driven by DMA interrupts.
