Support for Matplotlib 3.7.3+

[amoghcharan]

Tested locally for updated support of Matplotlib 3.7.3+ with patches.Rectangle() now requiring angle= as an input argument. This change also works with previous versions of Matplotlib (tested from 3.6.0+)

Current:
patches.Rectangle((x,y), width, length, angle, **kwargs)

TypeError: Rectangle.init() takes 4 positional arguments but 5 were given

Update:
patches.Rectangle((x,y), width, length, angle=angle, **kwargs)
