Pull Request Description: Add Support for Quectel-specific NMEA Sentences in pynmea2

Description

This PR introduces support for Quectel-specific NMEA sentences by adding new proprietary sentence classes under the QTM namespace. These classes enable parsing and handling of device-specific messages, such as GNSS status, configuration settings, geofencing, and more. This extends the library's capabilities for devices like Quectel's LC29H GNSS module.

Changes Introduced

• New Classes:

  • QTM: Base class for Quectel proprietary sentences.
  • Specific message types:
  • QTMVERNO: GNSS module version information.
  • QTMSAVEPAR: Save receiver parameters.
  • QTMRESTOREPAR: Restore receiver parameters.
  • QTMEPE: Outputs estimated positioning error.
  • QTMCFGGEOFENCE: Configure geofences.
  • QTMGEOFENCESTATUS: Geofence status.
  • QTMCFGSVIN: Survey-in mode configuration.
  • QTMSVINSTATUS: Survey-in status.
  • QTMCFGRCVRMODE: Receiver mode configuration.
  • QTMDOP: DOP values for GNSS accuracy.
  • QTMPL: GNSS protection levels.
  • QTMCFGSBAS: SBAS configuration.
  • QTMCFGCNST: GNSS constellation configuration.
  • QTMCFGFIXRATE: Configure GNSS fix rate.
  • QTMVEL: Velocity information.
  • QTMCFGODO: Configure the odometer feature.
  • QTMODO: Odometer status.

• Tests Added:

  • Unit tests for each newly implemented proprietary message.
  • Located in tests/test_qtm.py.
  • Ensures accurate parsing and handling of valid and edge-case data.

How it Works

• Dynamic Message Mapping: The QTM base class dynamically assigns the appropriate subclass based on the first data element (manufacturer + data[0]).
• Custom Parsers: Each proprietary message class extracts and validates specific fields, such as build_date, epe_north, geofence state, and others.
• Enhanced Repr Methods: Custom __repr__ implementations for better debugging and logging outputs.

Checklist

• [x] New tests added for each message type.
• [x] All tests pass locally with pytest.
