Update innotronic creation

[JensOgorek]

Motivation

Adapt to the updated Lizard InnotronicDriveMotor module. In addition, motor currents are now included in the core output so that current monitoring and debugging are possible at the application level.

Implementation

• InnotronicTracksHardware updated to the new Lizard module signature (construction via InnotronicDriveMotor(can, node_id) and InnotronicWheels).
• core_message_fields extended with left.current_m1, left.current_m2, right.current_m1, right.current_m2 (4 values, 2 per side — the Innotronic driver reports the current of motor 1 and motor 2 per module in amperes).
• handle_core_output stores the four current values in left_current_m1, left_current_m2, right_current_m1, right_current_m2.

Note / Follow-ups

If further values from the Lizard module are needed (e.g. status flags, temperatures, position ticks), they have to be added analogously in core_message_fields and handle_core_output. For now only the currents are exposed — sufficient for initial logging/debugging; more can be added on demand.

Progress

• I chose a meaningful title that completes the sentence: "If applied, this PR will..."
• I chose meaningful labels (if GitHub allows me to so).
• I documented breaking changes and set the 'breaking change' label if needed
• The implementation is complete.
• Tests with a real hardware have been successful (or are not necessary).
• Pytests have been added (or are not necessary).
• Documentation has been added (or is not necessary).
