Resolve Duplicate Phytanoyl-CoA Alpha-Oxidation Reactions

[Devlin-Moyer]

Main improvements in this PR:

As proposed in #775:

• Removes MAR05187 for being a duplicate of MAR03486 + MAR03386
• Removes MAR05186 for being a misrepresentation of the catalytic activity of ALDH3A2
• Changes the GPR of MAR03386 to ENSG00000072210
• Removes ENSG00000182591 from the GPR of MAR03486
• Removes ENSG00000182591 from the model entirely because it's not known to catalyze any reactions

I hereby confirm that I have:

• Tested my code on my own computer for running the model
• Selected develop as a target branch
• Any removed reactions and metabolites have been moved to the corresponding deprecated identifier lists
