Tightened B vertex chi2 cuts in three- and four-body IDDL spruce lines and loosened hadron IP cuts in four-body IDDL spruce lines to match the cuts between HLT2 and sprucing

To check rates, I ran over 100000 events using this script: https://gitlab.cern.ch/lhcb/Moore/-/snippets/3292

To calculate bandwidth, I assume an input rate of 75kHz and using that the output DST file is 45/48 MB before/after the change. I've been told this is not quite accurate as there is quite a lot of overhead in the DST. Anyway, here are the numbers:
