Enable CMake Support

Changes:

• Removed all Arduino specific function calls - MCP2515_Config now uses the micros function passed in by the user instead of millis().
• Added CMakeLists.txt

Testing:

• Changes have been tested with an implementation of the Kocherga Bootloader for the RP2040 Microcontroller.

Can you add a CI workflow for performing a simple smoke test, I.e. build this library? For inspiration you can take a look here:

[joerossrobotics]

I've implemented the smoke test

[aentinger]

This fixes #92 .

God, this was a mess.

@joerossrobotics please test.

I've just realized these changes have zero correlation with the purpose of this open source project but just fit your very narrow scope. Furthermore you're using this for a commercial product so I am basically helping you for free ... 🤦‍♂️ . If you want custom work, you can contact me for a paid contract.
