TAE activity filter

First implementation of a TAE activity filter based on long tracks.

An alternative filter based on VELO tracks is implemented in case it is needed for the start of data-taking - it can be enabled by switching the `use_long_tracks` to False (an example sequence is provided in this MR).

To be tested with MooreOnline!329 (merged)
