Version 1.8.3

• Fix a bug in tsdisplay where a value of lag_max larger than the length of the series would create a cryptic numpy broadcasting error. This precondition will still cause an error, but now it is one the user can better understand. See #440

• Change numpy pin to numpy>=1.19.3 (and build on lowest supported version) to no longer limit users' NumPy versions. This addresses #449

• Fix a bug where scikit-learn version 1.0.0 was raising ValueError when calling if_delegate_has_method, addressing #454
