Features
- Reduced version requirements in dependencies. `Python 3.8` is now the minimum version, rather than the only version available.
- Added a wrapper for picks `Picks`, which allows you to conveniently work with values (in samples, ms, mcs), colors, and meta-information.
Desktop application
- Added the ability to work with several picks: picks obtained by a neural network, completely manual picking, picks loaded from headers, as well as aggregation of several picks.
- Advanced export customization options.
