reformat.pl puts #=GC at top, should be at bottom

[dstern]

:exclamation: Make to check out our User Guide.

Expected Behavior

#=GC line is recommended at bottom of alignment (https://en.wikipedia.org/wiki/Stockholm_format##=GC) Does not seem like big deal, but causes alphafold2 to crash, because af2 expects #=GC at bottom (in their module remove_empty_columns_from_stockholm_msa - https://github.com/deepmind/alphafold/blob/0be2b30b98f0da7aecb973bde04758fae67eb913/alphafold/data/parsers.py) This is a problem when using custom multiple sequence alignments as input.

Current Behavior

in conversion to Stockholm format, #=GC RF placed at top of alignment
