Micropython_MCP2515

Micropython driver to communicate to CAN buses using MPC2515 via SPI port.

This driver is based on capella-ben' microPython_MCP2515 as well as Adafruit_CircuitPython_MCP2515 driver.

I modified here and there to:

1. Add the capability to set crystal baudrate (8MHz, 10MHz, 16MHz)
2. Simplify the lib files
3. Add config file for easy testing
4. More examples

Go check Adafruit_CircuitPython_MCP2515 for further implementation.
