Quick multimeric template mode doesn't support homo-oligomers

[jkosinski]

This code:

AlphaPulldown/alphapulldown/utils/multimeric_template_utils.py

Line 48 in 13d2c71

if protein not in parsed_dict:

only keeps one template per protein. Thus, one cannot use multimeric templates for homo-oligomers, e.g.

uniprot1,templ.cif,A
uniprot1,templ.cif,B
uniprot2,templ.cif,C

would only take chain A and C
