A Mongoose OS SD library based on the SD Card example
The SD can be interfaced with the ESP32 using either the dedicated SDMMC or the SPI peripheral.
If using the SPI interface, the pins should be defined in the application's mos.yml
The default configured pins are those used by the Lolin32 Pro board.
This version is compatible with Mongoose OS version >= 2.19.0.
The C API is described in mgos_sd.h.
RPC services are provided by rpc-service-sd
