Draft: Removing persist reco and only adding certain types of tracks in order to reduce BW

Description

This MR is intended to reduce the bandwidth consumption of the trigger lines in the b_toxll_hlt2_mva module. It will:

• Turn off persist reco
• Add a rd_get_tracks function that will provide, to all the lines, only tracks needed by physics analyses.

Bandwidth

The bandwidth was measured by running this snippet over 100K events in data but ONLY for the lines in b_toxll_hlt2_mva. The resulting file sizes were:

#	Kind	Uncompressed	Compressed
1	long	4.0M	2.3M
2	long_calo	7.6M	3.5M
3	long_calo_velo	11M	4.4M
4	long_calo_velo_pvs	11M	4.4M
5	long_calo_velo_pvs_upstreams	12M	4.6M
6	persist reco	20M	7M

The compression was done with zst -3.

Rates

The rates were tested with two configurations and they were seen to be unchanged, these are:
