UDEs working with experiment with different MB (#122)

Fixed a few bugs in the UDE workflow. The UDEs work suprisingly well with a different MB model. This means that using surface velocities is really a well proxy, which is robust to changes in surface elevation.

## ODINN v0.1.0

First release

**Closed issues:**
- Implicit method needed to solve the SIA (#1)
- Global Parameter setting file (#3)
- Mass balance needs to be added in small timesteps in forward model (#4)
- Use Sparse Arrays for glacier matrices (#5)
- Create fake A(ELA) function (#6)
- Generate training dataset with fake A function (#7)
- Train UDE on A for the SIA PDE (#8)
- A as a function of long-term temperature (#9)
- LoadError: Mutating arrays is not supported using Zygote (#10)
- Include different numerical methods in the DE solvers and add them as parameter options.  (#11)
- Initialize UA with stable value (#13)
- Physical constrains in the NN (#17)
- Investigate use of batches for UDE training (#18)
- Optimize code with `SparseArrays` (#19)

- Formalize Python and OGGM installation and folder structure (#30)
