- Use SD_SECTOR_SIZE define instead of magic number 512
- Replace uint8_t buf[1] with plain uint8_t
- Check sd_spi_read_dma precondition that sd_dma_context state has to be
DMA_IDLE explicitly and return false instead of relying on assert
- sd_spi_dma_isr is time critical

Add rp2 PIO and DMA fast SD card driver
...
The builtin micropython SD card driver using the default micropython SPI
implementation suffered from very low read speeds. Add an optimized SD
card driver using rp2 PIO and DMA. Currently read only, write support to
be added later.

Usable mfrc522 code.
...
Not as async as possible, and definately needs a future revisit. But
works for now, with acceptable delays, if the newly introduced
tocard_retries parameter of class MFRC522 is used and set to a
reasonable low value.
