Bugs for protein input

[Xinpeng021001]

@prihoda Hi! I may find a bug that:

The output file (*.bgc.tsv) does not have "protein_ids bio_pfam_ids pfam_ids" (empyt), no matter use protein file (--protein ) or change the protein file into gbk file (deepbgc prepare).

Besides, if use the protein sequence as input or change the format into gbk using --prepare, the deepBGC seems to treat the whole genome as one contig, which may cause some errors.
