Bug correction and interface improvement in main samir code. Improved output plot scripts (some work left to do). Various small improvements.

Added parcel mode outputs, improved docs, improved samir parame tests, minor corrections and changes.

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 more input preparation functions for parcel mode, started writing a global input preparation script. Reused script from modspa for config file.

Finished ndvi extraction scripts. Added parcel mode to weather scripts. Wrote script to convert dataframes into xarray datasets for parcel mode.

Started working on modspa parcel mode. Rewrote pre-modspa functions for better integration to modspa pixel. Improved efficiency and simplicity at the same time.
