Add feature that allows FE class to query HwCtrl for specific features

Depending on FW or HW some FE configuration might need to be altered. Should implement a FE and HwCtrl agnostic channel for the FE to ask the HwCtrl if certain features are supported. Should probably use string a json based exchange.

For example: RD53A can be readout with different speeds and number of lanes depending on what the HW supports. This requires the FE config to be altered to the specific values.
