Useful enhancements

[JA-Lacey]

Hey @kristyhoran List of potential enhancements that could be useful to implement for bohra we have discussed.

1. make bohra compatible using a contigs only set of inputs - that way can be used for just reference sequences etc.

2. be able to point to a pre-exisiting kraken outputs in the same way as ---contigs (-c) is used (Kraken is the slowest step after genome assembly so this could speed up run times if kraken has been previously run outside of bohra)

Thanks

@JA-Lacey can you please break this into separate issues and assign Krsity and label as Enhancement. and then close this issue?
