SPATEM/MAPEM Support

[lreiher]

This PR finally brings the long-anticipated support for SPATEM and MAPEM.

Relevant Changes

• newly generated packages etsi_its_spatem_coding, etsi_its_spatem_msgs, etsi_its_spatem_conversion, etsi_its_mapem_coding, etsi_its_mapem_msgs, etsi_its_mapem_conversion
• major switch back to codegen-py
  • codegen-rust (originally added in Alternative gen for .msg and conversion headers #17) is now only used to generate the CPM TS, as the Python asn1tools does not support the ASN.1 CLASS keyword
  • all other message types are processed using the original codegen-py
  • the main reason for switching back is that codegen-py is better maintaineable for us core maintainers; adding support for SPATEM/MAPEM was way easier here
  • this change is causing some breaking changes in existing message types, see below

Limitations

• RegionalExtension is not yet supported

[lreiher]

Add samples for SPATEM and MAPEM to etsi_its_msgs_utils.

[jpbusch]

It's not that easy, I would prefer to do it with the plugin MR.

[lreiher]

Test with naive sample or test with recorded MAPEM/SPATEM, then implement more advanced sample in visualization PR.

Also mention limitations in README?
