Qslib

- Units throughout protocols, thanks to Pint: you can now use strings like '1 hr' or '52 °C' when defining protocols.
- Automatic connections throughout Machine and Experiment, by default.
- Change safe titles from spaces-as-"-" to spaces-as-"_", consistent with machine.
- Deprecated paramiko tunnel.
- Documentation rewrite
- Implement EDS-file (in-progress and complete) synchronization for monitor.
- Reorganization of modules: common is no longer needed

- Allow setting of Experiment.sample_wells.
- Improve plotting code.

- Much faster `Experiment.sync_from_machine`, only transferring additional log
entries rather than the entire log.
- Common plotting routines for fluorescence data.
- More reliable monitoring.
- More reliable connections, and testing.
- `Stage.stepped_ramp` convenience function.
- Fixes to bugs inhibiting exposure setting, and some basic
implementations for this.
- Fixes to qs-monitor for cycle counts > 999 (and other large stage / step /
cycle counts).

- CLI improvements.
- Fix qs-monitor and various functions when run titles have spaces in them.
- Improve tests and typing.

- Add qslib CLI, with some basic utility functions.
- Include calculation using 1.6°c/s ramp (standard mode default) in
temperature protocols, initiating from 25°c. This makes experiment
temperature data match reasonably well with protocol calculations.
It needs to be expanded to handle different ramp rates and run
modes, however.
- Added some tests.

- Add internal SSH tunnel support, so that this doesn't need to be set up
separately, and can be configured with parameters to Machine.
- Fix mid-run syncing bugs related to directory creation.
- Handle some different inputs for Protocol creation.
- Try to handle spaces in names better; this is still a problem, howver.
