routine. Fitting with priors does not work yet.
* refactor: correlated fits without priors work now.
* refactor: prior error propagation and dof fixed.
* refactor: old prior fit implementation moved to tests.
* refactor: moved _extract_val_and_dval out of least_squares.
* refactor: comment removed.
* tests: additional tests and exceptions added.
* tests: test for constrained prior fit added.
* docs: least_squares docstring extended.
* fix: linting errors fixed.
* feat: additional if cause for fits without priors added to achieve
original speed.
* tests: test_constrained_and_prior_fit fixed.
* fix: fix array cast of least_squares dict mode.
* tests: test for lists in dict fit added.
* fix: additional asarray added in resplot.

* refactor: _standard_fit method made redundant.
* fix: xs and yz in Corr.fit promoted to arrays.
* fix: x promoted to array in _combined_fit if input is just a list.
* feat: residual_plot and qqplot now work with combined fits with
dictionary inputs.
* tests: test for combined fit resplot and qqplot added.
* docs: docstring of fits.residual_plot extended.
is ill conditioned with respect to the machine precision.
Criterion for warning for ill-conditioned covariance matrix changed to cond > sqrt(eps)
Test added.
