…es, such that recharge agrees better with HYDRUS results for short, synthetic LGARTO tests. Also re introduced free drainage as a lower BC for LGAR mode, where most of the development for this was done in 2022.

…O to main. Here, I have included a notebook called LGARTO_demo, in tests, that demonstrates that there are not significant changes between LGAR and LGARTO with TO_enabled set to false. I have included the stability tests, which currently yield no unstable model runs over 160k parameter set and forcing dataset combinations, across both options for TO_enabled. I have also included notebooks that compare HYDRUS and LGARTO results for 4 short, synthetic simulations, and 4 year long simulations using real forcing and soils data from USDA SCAN sites. Finally, I have added notebooks that animate LGARTO simulations, which helps a lot with visualization and communication. Also minor edits to documentation of lgar.cxx, and moderate edits to the readme in the tests directory.
