Actuator parameter data structures should accommodate drive line specific parameters

[d-loret]

Currently, there exists a fastcat::Actuator::ActuatorParams struct which contains the configuration parameters for the Elmo drives. However, this structure and the mechanism that leverages it does not currently support parameters specific to the Gold line or the Platinum line. Such parameters might be added in the future, and this should be accommodated for.

This issue should be taken into consideration in the upcoming configuration parameter infrastructure revamp in Fastcat. I think it should be addressed there.
