Full arguments support for Protobuf MCAP writer in Python

[IvDmNe]

In Python Base MCAP Writer class supports many arguments in it's init method.
But a Protobuf MCAP writer has only output stream argument. So, now If I want to have MCAP file with LZ4 compression, I need to get it from protobuf mcap writer with ZSTD compression and then use CLI to convert the file to LZ4. Also, chunking options are not available.

I think it would be nice to be able to pass all arguments of default Writer also to Protobuf Writer. Is this feature planned to be added?

If no, and If you think it's worth to be added, I can make a few changes and create pull request.

Possible solutions:

• make similar arguments of base writer to Protobuf writer and pass them in init function;
• make Base Writer a parent class of Protobuf writer (Were there any reasons that protobuf writer was created as a wrapper of base Writer instead of using inheritance?)

Yep - this makes sense, thanks for the suggestion.
