WIP: Update lstchain to v096...

[garciagenrique]

...onto the lstchain_io_RTA branch.

Full changelog between lstchain-v0.6.3 and lstchain_io_RTA branches:
cta-observatory/cta-lstchain@master...garciagenrique:cta-lstchain:v063_RTAv042_ped_ugly_fix

Changes:

• merge v0.9.6 branch plus solve conflcits
• take out rta-dependent dl2_to_dl3 scripts (Adapt RTA dl2-dl3 script and tools into RTA branch #3)
• adapt dl2_to_dl3 tools (Adapt RTA dl2-dl3 script and tools into RTA branch #3)e
• take out /scripts/data_selection_cuts.json (to be confirmed @scaroff) --> Or to be substituted by dl3_tool_config.json file
• remove rta-lst reorganiser (managed by HipeRTA_streaem now)
• check reorganiser with new ctapipe and lstchain versions (done - surprisingly same output, no need of updating nothing 🥳 !)
• Check/Change default standard configs.

Important Notes

• ctapipe_io_mchdf5 won't be any longer working (ctapipe=0.12 has evolved a lot). Nevertheless, we should start using the simtel --> hdf5 conversion provided by ctapipe >=v0.13.0 link. This means that:
  • The new env won't be able to make the conversion until lstchain gets updated (v0.9.7?) and incorporates ctapipe v0.15.0 Work in progress.
  • However, this update depends on ctapipe_io_lst and some dependencies updates WIP here.
  • This will take some time so until this happens and we can use the ctapipe R0-HDF5 conversion, ctapipe_io_mchdf5 will not be installed in the new RTA environment (thus, to create again the HDF5 files, if ever, an old env should be used).
