Need to add HoughCircles to grip

[RyanWangTheCoder]

It is a nice tool. We used in last year's FTC code.
This season, we need HoughCircles in grip. It seems it is not available. Any info or example on how to add it?

It has been quite a long time since I've worked on this project. I'm more than happy to review and merge a pull request that adds the feature if you wish

any help on how to add this function in grip?
