apply icc profile to output

## Issue or Feature
- [ ] I have some PNGs with custom ICC profile (Display P3 or DCI-P3: I'm guessing they're the same?), which I'm stacking on a Canvas, but I'm unable to set this same icc profile when saving the result into a file
- [ ] how can I apply the proper icc profile ?

I did try following [this](https://github.com/WICG/canvas-color-space/blob/main/CanvasColorSpaceProposal.md#color-spaces), but it does not seem to be supported:
```
const ctx = canvas.getContext('2d', { colorSpace: 'display-p3' } );
```
