Fix typo in bounds calculation
minor bug fixed
Added the sentinel-like experiment, but with MODIS. Need to complete the blurb and also try the S2 bands
Issues to be tested when two parameters are regularised
Added the spatial smoother, and also some changes to the prior sign so that it actually works...
Operators have now been upgraded to deal with spatial observations too (I think). I also need to see whether it makes sense to pass the derivatives vector from state, as it saves with calculating its size
