NDVI and Weather preprocessing update. Fixed both pixel and parcel mode, smoother and faster processing. Data download and processing is functional. Parcel mode has received a large update. Environment file updated.

Added THEIA and LandSat image download and management. Improved and simplified input preparation for parcel mode. Rewrote model calculation memory estimation function. Corrected small bugs.

Bug correction in shapefile conversion, improved parcel output results. Pixel and Parcel results now match relatively well. Added a method to add output parcel data into the shapefile, method to improve (it's too slow and produces huge files as outputs).

Memory optimisation, improved speed and memory usage. Minor modifications in input preparation. Rain data is now scaled by 1000.

Various modifications in preprocessing codes. Improved datachunking, corrected bugs in weather dataset download, small improvements in script speed. Added a notebook to help prepare landcover and soil data for pixel mode

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

Partially fixed input weather data handling. Found a way to convert tifs to netcdf. Modified functions accordingly. Sequential optimisation of code well advanced, will try multiprocessing after.

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

Changed weather data loading to geotiff (can't find tool to convert tif to netcdf for large datasets), rewrote some function description, minor refactoring.

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.
