Species

- Replaced `wget` with `urllib.request`.
- Warnings and errors added to `add_model`.
- Compatibility of `get_data` with the petitCODE spectra.
- Several small updates in the code and tutorials.

- Updated tutorial notebooks.
- Several minor changes and improvements
- ``ReadColorMagnitude`` and ``get_color_magnitude`` are compatible with photometric and spectral libraries.

- Removed the `config_path` parameter from `SpeciesInit`.
- Added notebooks with tutorials to the documentation.
- Updated documentation and some code maintenance.

- Major maintenance of the package.
- Documentation added for many classes and functions.
- Unit test added for the reading modules. Code coverage is ~50%.
- Several arguments have been changed to more descriptive names.
- Refactoring of `FitPlanck` which supports fitting a combination of Planck functions.
- Added the `field_range` argument for plotting color-mag and color-color diagrams.

- `resample_spectrum` for smoothing a spectrum.
- `quantity` argument in `get_model` to either output a flux or magnitude.
- Additional options in `add_calibration` for importing a calibration spectrum.
- Both field and young/low-gravity objects can be selected with `object_type`.
- `weighting` argument in `FitModel`.
- `ReadPlanck` for reading a Planck function.
- `FitPlanck` for fitting photometry and/or a spectrum with MCMC.
- Improved plotting functionalities.
- Many small improvements.
- Several minor bug fixes.
- Updated companion magnitudes and distances.
- Updated and improved documentation.

- Compatibility with petitCODE atmospheric models (clear and cloudy).
- Function to create color-color data from isochrones.
- Option to include isochrone data in color-color plot.
- Functions to return the most probable sample and the median sample from the MCMC results.
