Integration tests are minimal and will be followed up with another
ticket. The reason for this is that the RECV device talks to the
simulator that does not mimic the real behavior. This means that a
setting of RW point doesn't reflect in a R point change. This makes
integrating testing very limited in comparison to the unit testing.

L2SS-433: Add beamlet device, which takes over responsibility of all beamlet and bf_weight attributes from SDP

L2SS-358: Added APSCT and APSPU devices, their simulators. Added a common base image for the pypcc2 simulators. Separated station-dependend configs into separate CDB files. Added OPC-UA node path prefix to support instances with different paths to their nodes.

L2SS-391: Added StationControl device to control the lifecycle of the station (and potentially other top-level functionality)

L2SS-276: Initial implementation of XST device, made payload errors refer to FPGA they're from instead of which input they're for, and added subbands_calibrated flag to exposed SST parameters
