Improve ORF coordinates detection

[Donaim]

Instead of doing global alignment on whole genome sequences, align just the searched subtype ORF sequence to the full query sequence.

The searched subtype ORF sequence should be prefixed and suffixed with "+" to discourage spread of nucleotides.

The initial approach failed because of weird mafft behaviour.

Currently it seems like integrating mappy instead of mafft for this would be the best approach.

Need more investigation.
