refactor: clean input files
We tidy up the model input files which used to be scattered between lhc_pywit_model/data
, lhc_pywit_model/lhc_elements
and the example folders gathering all the ones which are typically not expected to change (e.g. HOMs, broadband contributions, machine layout..) into lhc_pywit_model/data
. In the example folders we leave only example-specific files such as the optics and the collimator settings. This will fix #22 (closed).
