Photometry copier

[oliche]

The photometry copier has a prototype.

A few questions still:

• I chose to validate thoroughly the neurophotometrics CSV using pandera this is a new dependency... I think this is worthwhile, but let me know if you have reservation and I can shelve the validation part
• the code to validate and read the csv is currently in iblrig, it may be useful to move it to ibl-photometry. But that means we will have to groom and prepare ibl-photometry as an iblrig dependency. This also means we get pynapple in our environment.

This would usually be a draft pull request, but here I see no harm in merging early as there isn't much impact on the other code.
