[FEATURE REQUEST] Using external gene clusters for anvi-pan-genome

[FlorianTrigodet]

The need

Let the user use their own gene clusters for anvi-pan-genome.

The solution

A flag for anvi-pan-genome to tell the program to not run diamond/MCL, but use a user-defined list of gene cluster. The final pangenome would have the exact same features with AA alignment, functions, homogeneity layers, etc.

Beneficiaries

I would really like that feature, but I'm sure other people would too :D
