v1.4.1

Added

• Created new sphinx documentation, replacing the old Jekyll documentation.
• Added HISTORY.md file for recording history (now CHANGELOG.md).

Changed

• Reword some error/warning messages, now less opinionated and more concise.
• Some attributes have been renamed to be more ambiguous in the hopes more Model Architectures get
  supported in the future.

Fixed

• Fix model chaining. It now gets the correct model and model scale values for each FrameEval call.
• Fixed the pytorch extra group to correctly be optional and correctly reference a dependency.
• Some type-hinting has been corrected.
