- Fixed bug in fct that get/insert ref genome - there were pbs with the conditions, with the md5 as pk and not id
- Changed the restriction on the ref genome collection: name unique_with md5
- Introduced multiplex lib and search on that table and logic around it in db_oper, entities, tasks and statuses
- Introduced hgi-project field as mdata, + logic around it regarding extracting the prj name given the path
- Modified tasks.py: solved small bug and refactored some code around sample and lib (unknown field) + query multiplex lib table
