Feature Request one trc file per test case

[Pog3k]

in order to have one trc (Can Log) file per test we want to add an option to do that.

Currently we have also have the TRC Merge which is always on per default.

From Discussion

• Enable/Disable auto merge shall be possible.
• It could be that the pcan drivers allows to force creating new TRC file without opening/closing the connection to the pcan.

• Additional pcan connector api could then be added start_trace(trc_name: str | None) and stop_trace()
