Remove old picca routines [bump major]

[Waelthus]

This PR intends to remove old picca routines, such as picca_deltas and picca_fitter2 with their dependencies (but leaving the parts that correlation function and p1d still need). Adresses #1032

[Waelthus]

It's expected that code testing coverage will change, I'll use that as a hint regarding which parts may be removable e.g. in picca/{io.py,prep_del.py,...}

[iprafols]

io.py will definitely not be removable since it is also used for the computation of the correlation function. Maybe for now we can just remove picca_deltas.py and the tests associated with it. We might as well remove the fitter2 now that we're on this. We have also been using Vega for a while now

[Waelthus]

yes, I know that it won't be fully removable, but the other files regarding deltas will be. And for io I'd at least remove a bunch of spectra-read-in (read_data, read_from...) functions, but will keep deltas/objects/dlas/absorbers/drq alive.

[Waelthus]

fitter2 is already removed here

[iprafols]

cool, makes sense

[iprafols]

looks fine, I see that you did not remove the bits of code from io.py and the rest. Maybe you can also remove the fitter2 folder

[Waelthus]

Most legacy code that isn't used by for cf et al is gone. Parts of data.Forest are still there as cf hijacks it's variables, prep_del is only kept for stacking, raw_io is kept in case it's still needed (as we don't test it afaik).
We might want to have a test of non-automatically tested parts of the code, e.g. dmat or wick

Which version do we want? 8.0 as this is breaking all bw compatibility to old picca?

[iprafols]

I'd say to go to version 8, yes. It does make sense to keep the raw analysis for the meantime (maybe we should try to migrate it to be part of the delta_extraction code at some point. Also, I totally agree on having tests for the missing parts.

I see that the test suit has changed. Was this needed due to the library changes that made the tests fail?

[Waelthus]

Ah, I originally thought I could remove everything related to picca_deltas tests. Just to figure out later that those files were partially inputs of the cf and p1d tests, so one commit needed partial revert... In the end it should be removals of files and code only (and changing some comments). Am 1. August 2023 17:25:08 MESZ schrieb "Ignasi Pérez-Ràfols" ***@***.***>:
