I had been meaning to ask you about this. I found some odd behaviour with the seq_table_from_rows() method - perhaps I'm not quite using it right.
seq_table_from_rows(SeqTableRow(), SeqTableRow())
The above works as expected but the below raises an error:
rows = (SeqTableRow(), SeqTableRow())
seq_table_from_rows(rows)
AttributeError: 'tuple' object has no attribute 'repeats'
When I looked into it I found that inside the method, rows gets turned into ((SeqTableRow(), SeqTableRow()),) - A tuple within a tuple. So my workaround was to check if the first element in rows was a tuple, and to use that instead.

We shouldn't import epics from fastcs. Can we use INENC1.VAL.Scale from PandA instead?

These changes implements a Panda Trigger Logic Flyer, setting up a PandA Seq table and resolves #448. On Prepare it takes a Spec[motor.Motor], which would describe the trajectory of the scan, and uses this to calculate the gaps in the scan. Between each gap it will setup a new set of rows in the sequencer table.
