Assure that target_subfragment is always one single value

[antgonza]

We should add a check to make sure that target_subfragment is always one single value per prep info file.

This came to play when loading redbiom (found by @wasade) and some studies/prep-infos had multiple target_subfragment.

Tis is usually a fill-down error and easy to fix but very good to catch.

@charles-cowart, this can be solved as part of #2799; basically, the idea is that during the prep validation we check that the target_subfragment, target_gene and platform columns only have 1 value.

This was solved in #2881
