Add DSMR5 option to protocol.

This will allow support for: home-assistant/core#7535

Currently i'm assuming V5 serial settings are equal to V4. I will ask users to test.

@ndokter I've seen you have been working on automatic version detection. Nice. I have been pondering that feature for a while. I will keep an eye on it and add support for HA when it is released.

[ndokter]

Thank you for the pull request. Ive merged your changes and uploaded a new version to pypi.

The automatic detection is nice, but im not sure what kind of object it would return. Maybe not just a simple dict.

Currently not working on dsmr-parser so much :)

[aequitas]

Probably because it is already perfect ;) I'm waiting for some people with DSMR5 to confirm the changes work as expected, if not there might be another PR in a few days.
