This MR adds a few things:
- A test for SpsStation which verifies we can initialise, then synchronsise TPMs, and that various register values are correct.
- Change the initialise procedure slightly such that we set src IPs before we initialise the tile, for use during initialisation. This gets rid of the long wait time seen at AAVS3 after initialise finishes before we can synchronise. (https://jira.skatelescope.org/browse/MCCS-2114)
- If not given a start time, SpsStation StartAcquisition will now get a start time at execution, rather than just before queuing.
- SpsStation.DescribeTest(test_name), grabs the doc string of the relevant test.
