Add support for complex channel names in ASC files

Is your feature request related to a problem? Please describe.

We encountered an ASC file that contains channels names like Li:

  42.017364 Li 14              Rx     8 2a 79 00 00 00 80 c0 ff  checksum = 07   header time =  40, full time = 135  SOF =   42.010348   BR = 19200  break = 942203 109234   EOH =   42.012418    EOB =   42.012979    42.013527    42.014075    42.014623    42.015172    42.015720    42.016268    42.016816    sim = 0    EOF =   42.017364   RBR = 19157  HBR = 19202.640363  HSO = 22785     RSO = 22837     CSM = enhanced

The current ASC reader fails to parse these files, i.e. it skips these messages because channel has to be an int.

Describe the solution you'd like

Would it be possible to enhance the ASC reader to deal with the complex channel names?

That's a LIN channel, not a CAN channel.

This makes a lot of sense ... Thank you very much.

Do you think it is feasible to support LIN channels as well for ASC files? I know this is CAN library but it is the best reader for ASC files for Python.

[zariiii9003]

But what are we supposed to do with these lines? It does not make sense to return can.Message instances for LIN messages.

I see. We would need a lin.Message. Probably beyond the scope of this library.
