Mhcvizpipe

Changed

- Added the option to change the maximum "acceptable" peptide length. This can be set in the Settings window.
The first time you run MhcVizPipe after this update, you will need to add the parameters to the settings
by clicking `LOAD DEFAULTS` in the settings window.

Missed these updates in the changelog...

Changed

- Added version number to the GUI and report headers.
- UpSet plot is now left in sample order, not order by decreasing cardinality.

Changed

- Refactored a lot of things to improve the Windows standalone version. It now only runs the DTU Health Tech tools
with WSL, rather than everything.

Fixed

- Removed unused matplotlib imports

Added

- Added a changelog!
- GibbsCluster will no longer be run when there are fewer than 20 peptides. This will hopefully prevent it from getting
stuck.

Changed

- You can now give different alleles to each sample.
- Individual samples can now be deleted after you load them.
- UpSet plots are now generated with [UpsetSetPlotly](https://github.com/kevinkovalchik/upsetplotly). This allows us
to use Plotly for all the figures, and also makes the report more consistent in style.
- Some simple quality metrics have been added: LF Score (length fraction) and BF Score (binding fraction).
- LF Score = the fraction of peptides with a length of 8-12 mers (for class I) or 9-22 mers (for class II).
- BF Score = the fraction of peptides which are predicted to be weak or strong binders for at least one allele.
- These scores have been combined with the "sample overview" table.
- There is a color gradient applied to the cells containing these scores. Green = "good", red = "bad".
