This is pretty much the same fix applied to f-BRS in #5384. We've been
using HRNet for a while and now an then we receive "500 errors" just as
reported in #5299 when someone forgets to drop the alpha-channel from
our images.
### Motivation and context
The RuntimeError is a little bit different, but comes from the same
issue: RGBA instead of RGB images:
> RuntimeError: Given groups=1, weight of size [16, 3, 1, 1], expected
input[*, 4, *, *] to have 3 channels, but got 4 channels instead.
### How has this been tested?
I created a task with images with and w/o alpha channel, and the
interactor works on both now.
* Added HRNet18 click based interactive segmentation (#3729)
The commit adds serverless container that has a click based
interactive segmentation model(HRNet18) that performs better than
f-BRS method statistically.
* fixup! Added HRNet18 click based interactive segmentation (#3729)
