Minor nit: functions should accept BaseException instead of Exception type

[zplizzi]

that way, you can do something like:

current_exception = sys.exception()
if current_exception is not None:
    tb = traceback_with_variables.format_exc(current_exception)

instead of currently needing to do

current_exception = sys.exception()
if current_exception is not None:
    tb = traceback_with_variables.format_exc(cast(current_exception, Exception))

and have the type checker be happy.

this makes sense more generally because there's no reason eg a KeyboardInterrupt shouldn't be handled with this library, right?

Thanks! Sounds valid, I'll update it this week
