Adding CAN FD frame support to asc writer

I think we should add some testing for FD if we add this. Like
(a) adding some example FD frames to logfile.asc and/or
(b) adding actual FD testing to logformat_test.py

Apart from that, it looks nice.

I will add proper tests as soon as possible...

I did a rebase but maybe some things need to be adjusted because the black formatter requires it.

[felixdivo]

I fixed the formatting. Apart for some tests, this can be merged.

This could also resolve the old #269.

I’m doing some refactoring of the blf module and in the meantime adding general CAN-FD testing capability.
