This step only handles FSW channels, which means you cannot check both FSW and SSE channels in the same step. this is quite limiting compared to the built in wait_eha step.
We will need to combine FLIGHT_TELEM and SIM_TELEM, so that an input control can handle either type.
Choice between FLIGHT vs. SIM would be done by the user through the UI.

We opted not to implement it this way because while AMPCS handles Flight/Sim telemetry together, other systems may not and forcing steps to support both Flight/Sim could cause additional burden.
I will also say that the actual use of mixed queries to both flight/sim is quite limited (~3% of Europa ALTO EHA steps) and the impact of using two steps with a common reference time is a low impact workaround.

This is an initial implementation of a Wait/Verify EHA for Flight Channels using the step framework.
It also includes an initial implementation of an ampcs library (functions to query GLAD).
There are some known longer term issues including:
