Add Support for Megasquirt Ecu

[TonyEvo]

Hi Timurr, I also wrote to you on the race chrono forum and you were very kind to answer me. As I mentioned, I would like to create my own project(not really mine, but for my ecu) to be able to read the Can Bus signals from my ECU (megasquirt 2, a widely used reprogrammable Race Ecu) to be able to read the values ​​also on race chrono, I wanted to know your opinion on the feasibility, in this screen shot there are the info on the Can signals.

P.S. I have already created a similar project with arduino (thanks to a friend who knows about code) and a mcp2515 and it seems to work, but it is a bit cumbersome and not very fast. However, since I also bought an nRF52832 and I have another MCP, I could try to create this project too and see how it behaves.

Hi Tony!
Since I don't have that ECU on my cars, I won't be able to effectively add support for it myself.

However, I'll happily accept a Pull Request if you send me one.
You can follow PR #7 as an example.
