Dart-id

* Hotfix: Add missing libwinpthread-1.dll for Windows users without MinGW/msys2 on their path.

* Validate configuration files with `jsonschema`

* Hotfix: Add extra filtering step to prevent potential crash during PEP update process.

* Hotfix crash when loading files without all DART-ID columns.

* Fix installation bug where default config file was not being included

* Add documentation website [https://slavovlab.github.io/DART-ID/](https://slavovlab.github.io/DART-ID/)
* Enforce minimum number of confident PSMs per experiment (to avoid accidentally aligning blanks, for example)
* Add config file with a bunch of sensible default options. These are loaded if the user doesn't specify them
* Accept DART-ID output files as input files. Just removes the DART-ID columns first
* Silence pandas deprecation error for pd.concat(...)
* Add verbosity levels, instead of just true/false
* More error tolerant figure generation. Now errors in generating figures shouldn't end runs.
