Change canvas aspect ratio based on loaded dataset

[ShrimpCryptid]

Use Case

Canvas aspect ratio is currently a hardcoded value (roughly 7:5). It would be nice to resize the canvas viewport based on the loaded frame dimensions of the dataset, so we minimize any gutters around the frame.

See line: https://github.com/allen-cell-animated/nucmorph-colorizer/blob/main/src/components/CanvasWrapper.tsx#L14

Acceptance Criteria

Please describe how you know this is done

Details

• Are dataset frames ever going to resize unexpectedly? Will this behave well for very long or very narrow frame sizes?
