[Feature Request] Support DW Open Pose for "Detect from Image"

[ghostsquad]

Is your feature request related to a problem? Please describe.

"Detect from image" is not as accurate as I'd like.

Describe the solution you'd like
DW Open Pose pre-processor seems to do a lot better than the standard open-pose preprocessor. I was wondering if it was possible to select the pre-processor when using the "detect from image" open

Describe alternatives you've considered
N/a
