Probeye

Changed
- fixed a bug with the probeye.txt file, which was missing in the build

Changed
- modified code format according to standard black and introduced type hints

Added
- added summary attribute to solver classes

Changed
- the evaluate_model_response method was moved from InferenceProblem to the solver classes
Added
- added integration test for maximum likelihood estimation with uninformative priors

Changed
- deep-copying the inference problem in the solver classes is wrapped with try/except, since not all problems can be deepcopied

Added
- added feature of vector-valued parameters
- added new ParameterProperties attribute 'dim' for specifying a parameter's dimension
- added explicitly defined Jacobian in test_linear_regression to show how a user can define the Jacobian to his forward model
- added new integration test 'test_multivariate_prior.py' to show use of vector-valued parameters
Changed
- changed PriorNormal to cover multivariate distributions
- moved 'probeye.txt' into the probeye directory
- the probeye_header function does not read from setup.cfg anymore (this file is not available after installing the package)
- more plots with different options are now generated in the integration tests
