- `SequentialStrategy` and `StreamingSequentialStrategy` classes
- Telemetry env variable `BAYBE_TELEMETRY_VPN_CHECK` turning the initial connectivity check on/off

- Bumped cattrs version

Fixed
- Now supports Python 3.11
- Removed `pyarrow` version pin
- `TaskParameter` added to serialization test

Changed
- Include linting for all functions
- Rewrite functions to distinguish between private and public ones
- Unreachable telemetry endpoints now automatically disables telemetry and no longer cause
any data submission loops
- `add_fake_results` utility now considers potential target bounds
- Constraint names have been refactored to indicate whether they operate on discrete
or continuous parameters

Fixed
- Random recommendation failing for small discrete (sub-)spaces
- Deserialization issue with `TaskParameter`

Added
- `TaskParameter` for multitask modelling

- Advanced simulation mechanisms for transfer learning and search space partitioning
- Extensive docstring documentation in all files
- Autodoc using sphinx
- Script for automatic code documentation
- New `tox` environments for a full and a core-only pytest run

Changed
- Discrete subspaces require unique indices
- Simulation function signatures are redesigned (but largely backwards compatible)
- Docstring contents and style (numpy -> google)

Added
- Test environments for multiple Python versions via `tox`

Changed
- Removed `environment.yml`
- Telemetry host endpoint is now flexible via the environment variable `BAYBE_TELEMETRY_HOST`

Fixed
