Collab B8 (mostly) done + Tests

Updated methods to comply with ICON v2.6.2. Docker Image is now pulled that tests if the code compiles and runs a simple example. Can read files from B8 and run simulations. Progressbar does not show up multiple times anymore, but rather the total amount of simulation steps is calculated and shown at once. Can now read files with NaNs every few time steps. Added more model parameters for tracking. Can now detect different phases of the trajectory. Only missing: Varied sensitivity calculations for different parameters. In principal, this can be done by hard coding the values.
