mokapot v0.8.0

[0.8.0] - 2022-03-11

Thanks to @sambenfredj, @gessulat, @tkschmidt, and @MatthewThe for
PR #44, which made these things happen!

Added

• A new command line argument, --max_workers. This allows the cross-validation folds to be computed in parallel.
• The PercolatorModel class now has an n_jobs parameter, which controls parallelization of the grid search.

Changes

• Improved speed by using multiple jobs for grid search by default.
• Parallelization within mokapot.brew() now uses joblib instead of concurrent.futures.
