Ice rheology inversions pipeline

We need a new modelling pipeline for the ice rheology inversions. Since the inversions will be based on the average ice velocities for 2017-2018 from Millan et al. (2022), we don't need a solver, and therefore we don't need to use a UDE.
Most of the work is already there, but some new features are needed:

Most of the work is already there, but some new features are needed:
- Think of which features will be relevant to infer
A
andC
from the SIA. Download and add that data as input features of the NN. - Re-design the NN architecture and hyperparameters with something more suitable for this task. The one we're using for the UDE is probably way too simple.
- Decide on the spatialization of the inversions.
C
will most likely have to be inverted in a distributed matter, i.e., an individualC
for each pixel. WhereasA
will probably make more sense as a unique value per glacier. - Anticipate issues related to equifinality. Try to constrain
A
in a more aggressive way, penalizing the use ofA
for fast surface velocities, which should in theory be described byC
