IOS: Request: More optional values in “Max features extracted”

[APOS80]

Hello again.

I think 1000 is to small and infinite is to high, I would like steps up to 3000 if possible.

Using too many keypoints clustered together does not actually provide more information. So I usually only use hundreds of high-quality keypoints.

Re-opening, as it is a small change to do.
