Update pharokka to v1.2.1

Describe your pull request here

Updates pharokka to v1.2.1. Minor change. Manual PR required as I am fixing an issue with bcbio-gff which breaks due to the newest update to biopython v1.81. Accordingly I need to add to the dependencies of pharokka an upper bound for biopython <1.81.
