Gnpy

This release introduces a major refactor that enables
a clear separation of design and propagation functions.
It also introduces some behaviour correction and bug fixes.

- fix frequency scaling for fibers
- fix documentation on readthedocs.io
- possible to freeze a design and propagate on it without automatic changes
- checking for power saturation during design for all cases

This new release adds some improvements in existing features,
and some new features:
- Spectrum assignment now supports multiple slots assignments
in a single request.
- Logs are now generalized in the library instead of bare
prints. Default verbose is "WARNING".
- Chromatic dispersion, effective area, Raman Gain coefficient,
and nonlinear coefficient can now be defined with a scaling
along frequency.
- Power equalization now enables defining a power offset
in transceiver library to represent the deviation from the
general equalisation strategy defined in ROADMs.
- Propagation now includes a latency calculation
- The library now supports of python 3.12

Starting with this release, the users can [define a mixed load of channels to be propagated in the input spectrum](https://gnpy.readthedocs.io/en/master/json.html#arbitrary-channel-definition). To better support real-life workloads, ROADM equalization strategies are now configurable, and there is also the usual set of bugfixes and performance optimizations.

Greetings from a sunny day in Basel, Switzerland. This is a general bugfix release with some preparations for the upcoming features (mixed-rate simulations and the YANG interface). Please stay tuned while we stabilize these, and try out our patches under review:

Hailing from the sunny Bordeaux, France, where ECOC 2021 is taking place, here's a new version of GNPy, an optical route planning library.

Released just three months after the v2.3, we've improved support of OpenROADM networks, fixed bugs, and extended our test suite. As was
previously announced, this is also the first release to require a more recent Python, the 3.8.
