Added xtal frequency table for 8MHz

[casainho]

This library did not work with MCP2515 modules with 8MHz xtal, only for 16MHz. I expanded the table to include the 8MHz. The default value still is the 16MHz.

I can not understand the existing errors on CI, can someone please tell me what I need to do??

You can run pre-commit locally to run black (the formatter tool) and let it reformat the code the way it wants, and then push those changes. That should resolve the CI issues.

Thanks @tekktrik. For some reason I could not find a solution, pre-commit is failing on my Linux Ubuntu 22.10. So I am not able to move forward with this.

What is the error you're getting?

Got it solved as it was the same that is as an alert on run pre-commit locally page.

Will push the little changes later.

So, all checks passed.

I hope this PR is on your interest and that you will accept it.
