v0.2.1

• BETA: in-silico mutagenesis using ProtTransBertBFD. This computes the likelihood that, according to Bert, a residue in a protein can be a certain amino acid, which can be used as an estimate for the effect of a mutation. This adds two a new mutagenesis and a new protocol plot_mutagenesis in the visualize stages, of which the first one computes the probabilities and writes them to a csv file while the latter visualizes the results as interactive plotly figure.
• Support half_precision_model for prottrans_bert_bfd and prottrans_albert_bfd
• Fix a n_components: 2 in the plotly protocol
