Cadet-process

Improve support for windows

Added
- Module for calculating buffer capacities
- String representation for chemical reactions using Component
information
- Made previously hard coded parameters configurable

Fixed
- Plot units for CSTR volume
- Checks in reaction module

Changed
- Construction of user_solution_times to avoid IDAS crashes
- Bump version for hopsy to support windows
- Component class constructor
- Module names to comply with PEP8 (WIP)

Improved Solution and component handling.

Added
- Classes for bulk, particle liquid, solid, and volume solution.
- Component classes used for tracking sub-species and naming.
- Methods to calculate adsorption and reaction equilibria.
- Binding: MobilePhaseModulator adsorption model.
- Cadet: Method to create CadetAPI object from hdf5 file.
- OptimizationProblem: parallel evaluation of populations.
- Pymoo: Resume optimization from checkpoints.

Fixed
- Correctly calculate flow rates for processes without events.

Changed
- Start of reorganization of `common` module into smaller dedicated modules.
- Discretization is now handled by UnitOperations instead of CADET-Adapter.
