Modification of SAMIR equations, use of Kcbmax instead of Kcmax. Plot_GIF modifications. Doc update.

Further improvements in optimization. Manage to create real empty output dataset and append values along the time dimension, greatly improves total run speed. Reworked the custom_input notebook for a better handling of the land cover class conversion. Added tests on parameters values to make sure they are in correct range, parameter ranges are defined in a csv file (params_samir_min_max.csv). Other small modifications.

Some optimization improvements. Potential memory leaks to look at. Many improvements in the preprocessing scripts, almost finished the parcel mode. New scripts in the prostprocessing directory. Changes in the samir parameter handling.

Added main_run_samir.py to run the samir model. Modified config_file to manage input paths. Various bug corrections in dataset dimensions, speed improvements with parallel processing parameters. Added a notebook in postprocessing to plot pixel model outputs.

Fixed equations, deleted some temporary variables to reduce memory usage, used eval() function to improve readability.

run_samir() operational. Outputs are not yet valid, updated dev_samir_xarray.ipynb for comparison with modspa excel and added validation inputs and outputs for comparison.

Modified input calculations. Reprojection of weather dataset needs to be handled differently for bigger images (with OTB for example). Modified the parameter class. Begining to work on samir time loop, inputs and parameters are done. Added env file. New method for calculating ET0 with xarray might have been found.
