New condensate-specific protein attributes

**New attributes for a condensate:**

1. protein_functional_type: dict
Key: Protein's Uniprot ID
Value: functional type in this condensate ("driver"/"client"/"regulator")

2. protein_driver_criterion: dict
Key: Protein's Uniprot ID
Value: criterion fulfilled to qualify as a driver ("self_ps", "induce_formation", "intergrity_essential")

3. protein_exp_evidence: dict
Key: Protein's Uniprot ID
Value: experimental evidence ("in_vivo", "in_vitro", "in_tergrity_essential_cellulo")
