Support Byron Addresses

[theeldermillenial]

Is your feature request related to a problem? Please describe.
Support Byron addresses and/or create a special error when trying to decode byron addresses.

Describe the solution you'd like
Ideally, Byron addresses should be supported.

Describe alternatives you've considered
As an intermediate solution, it would be helpful to have a special error to catch Byron addresses.

Additional context

I'm currently trying to use Oura from TxPipe to monitor all transactions. I get raw tx CBOR that I try to parse with pycardano, and when it encounters a Byron address it throws an invalid network validation error. A specific error when parsing Byron addresses would help as an intermediate solution to at least be more informative until full support of Byron can be implemented.
