FoRecoML 1.1.1

• Reworked the print() and summary() methods for rml_fit objects, which now return a more informative, structured overview of the fitted reconciliation (framework, machine-learning approach, problem dimensions, features, training sample size, combination matrix and trained models).
• csrml(), terml() and ctrml() now validate their arguments more strictly and fail with informative error messages that state the expected value and report the one actually supplied.
