@section History


5.0
- Bugfix: broke ESP8266 when I implemented this by using "__builtin_bswap32"
    a second time
- added wrapper_spi_transmit_32()
- changed return type of wrapper_spi_transmit_32() to void as intended
- added workaround for non-standard implementations of SPI.transfer(buffer, count)
- optimized for ESP32 by using SPI.write() and SPI.write32()
- removed the unfortunately defunct WIZIOPICO
