Support multiple instances of Telemachus antennae on a craft

[sidrus]

Telemachus should support multiple, independent telemetry feeds from individual antennae on a craft.
Version 1.x shared telemetry data streams across all antennae on a craft and that might cause issues when docking multiple craft together, where the combined craft may now have multiple Telemachus antennae.

• API will need to support getting a list of available telemetry feeds on a craft and their broadcast status (master, slave, active, inactive)
• Individual antennae should have a master/slave mode to support docking/multi-mode operations
• The craft will handle API requests from the master antenna
• Slaved antennae will enter standby mode upon docking.
