What's Changed
* Remove caching in https://github.com/gboehl/econpizza/pull/15
* We removed model & steady state caching, which is now left to the user. The reason is that this incraeased code complexity *a lot* without a clear advantage
* Some objects are renamed:
* after running a steady state search:
* `newton_result` is renamed to `root_finding_result`
* removed `values_and_pars` key in `steady_state` in favor of `all_values`
* added `solution_values` to `steady_state`
* allow `variables` and `parameters` to be specified as a dictionary. EP only uses the dictionary keys then, the values are being ignored. This can be used e.g. for defining latex strings per variable etc.
* rename `model['variables']` and model.variables to `model['var_names']` and `model.var_names`
* rename `model['parameters']` and model.parameters to `model['par_names']` and `model.par_names`
* variables in `decisions` -> `calls` are now always floats. Before, they were inconsistently 1D-arrays during steady state but floats during dynamics.
* Enable JAX persistent caching via `EconPizzaConfig` by shtopane in https://github.com/gboehl/econpizza/pull/17
