for WiFi buddy, we will be operating as a SPI target device, rather than as a SPI controller ("bus master"). i'm not sure OTTOMH if the esp32c3-hal SPI driver supports operating as a SPI target or if we need to write our own thing.
we may also want a driver where the C3 functions as a SPI controller, as well, to enable non-WiFi Buddy use-cases for MnemOS on the C3. but, this is probably lower priority than the SPI target mode.
we need to get SPI working so that we can talk to the D1 in the WiFi Buddy use case.
