Add `flow_to_image()` visualization util

See original GitHub issue

Now that RAFT is done, it’d be nice to have a conversion util from a 2xHxW flow to a 3xHxW RGB image. I think the implementation of the original RAFT paper follows a standard color map, so we could do something similar (trimmed down to the minimal parts, e.g. no BRG etc.) https://github.com/princeton-vl/RAFT/blob/master/core/utils/flow_viz.py

Note: this is a visualization util meant to land in torchvision.utils; it’s not meant to be a transform nor an ops.

I’ll be on holidays the last 2 weeks of Dec, so there’s absolutely no rush on our side 😉

Happy Holidays Nicolas. 😃

I will have a look at the script and try to implement a minimalist version. I will ping you back in a PR hopefully soon.
