Inmoose

- add a `data` module, with two RNA-Seq datasets: `pasilla` and `airway`
- fix build on readthedocs
- updated bibliography with our BMC Bioinformatics paper
- add verbose to consensus clustering computation
- add a utility class `VirtualCohortInput` to better check the well definition
of inputs to the batch effect correction routines

- fix syntax-impairing typos in `pyproject.toml`

- proper documentation for the `sim` module
- code is now formatted with `black`
- add a link to the documentation in the README file
- better handling of covariates in `pycombat` module

- add a function to generate simulated RNA-Seq and scRNA-Seq data
- drop support of Python 3.8 due to memory management issues in extensions
- add a module to perform consensus clustering and select the optimal number of
clusters

- `inmoose` now requires Python >= 3.8
- reorganize tests directory
- refactor module for batch effect correction. It is now named `pycombat`
(instead of `batch`), and the function to correct batch effect on microarray
data is now `pycombat_norm` (instead of `pycombat`).
- refactor design matrix computation, to share the code between `pycombat_norm`
and `pycombat_seq`
- batch effect correction functions now accept both `numpy` arrays and `pandas`
dataframes as input for the counts matrix
- improved logging: no more `print`s, better log formatting
- `inmoose` doc is now on `readthedocs.org`

- upgrade to Cython 3.0.0b2
- fix C++ extension loading on Linux
- add CI/CD to build, test and publish distributions
