v1.3.0

⚠️Breaking Changes

• D2V() object and loads now expect a path argument which may be None or a Path to a D2V object.
• load now uses the new _get_d2v() (explained below) on the input file path (unless it's already a D2V).

Improvements

• New static method _get_d2v() has been created, which can be used to generate a D2V for an input video file by path.
• Path to the input D2V file is now stored inside the D2V object for referencing (D2V.path). As stated above,
  D2V() and loads will now ask for an optional Path.
• All public-facing class methods now enforce the type of the arguments, as well as checks if the file actually exists
  and is not a directory.
• Variables formatted into D2V()s repr is now also using their reprs as well. This improves its readability.
• Use consistent double-quotes throughout pyproject.toml.
