Magphi

Fix bug introduced by v2.0.0. Now only allow reverse complement to reorient output sequences

It is swooping season!
The 'humble' Australian magpie is renowned for "swooping" (attacking) by passers during their baby season. In honour of the magpie swooping season we overhauled `Magphi` and implemented some changes to make it a bit easier to use outputs and increase its scope of use.

What's Changed
* tblastn implemented as alternative to default blastn. This allows the use of amino acid seeds using -p. Thanks to Andrew (BiologicalScientist)
* Default behaviour is now to reorient fasta and gff files based on the same seed across genomes. This the same orientation in relation to stand and sequence, allowing for easier alignment of outputs.

This is a tag bump to mitigate a PyPi upload hiccup

This release is the first following peer-review in Journal of open source software.
Main things changed are documentation.

Release include
- Better toy example with gff and a draft genome
- Doc-strings for all functions
- Paper edits

This release include an informative README file, a better exit when samtools faidx fails on an illiegal fasta file, and initial unit tests for converting BLAST xml to a bed file.
