Jackal28 / MCP3304

MCP3304 ADC code to return different results based upon selected usage without having to have specific pins listed in SPI. Basically, its a bitbang version of MCP3304.

I created this file as a method to read the MCP3304 on the Raspberry Pico as none of the SPI versions would compile correctly. With this library, the initial pins are stated in the beginning instead of using a hardware SPI. It is based off of the Arduino Reference MCP3208 example.
