Feature request - masks from apertures

[keflavich]

This may be better thought of as a pyregion issue, but it is relevant to the existing photutils setup and highlights some of the overlap between the two packages.

I would like to be able to return a 2D mask from an image given an input aperture (either Sky or pixel). Both a boolean mask (containing all overlap or all contained pixels) and a floating-point fractional pixel mask could be useful depending on the situation.

This is also related to #161, but specifically about 2D masks.

@keflavich This is a good suggestion and it was actually how I thought about approaching #161. I've been a bit swamped lately, but I hope to get to this soon.

I was just looking for this feature and sad to find that it does not exist...

[larrybradley]

Patience, @pllim. I'm working on it.

So far, I can get around it by getting the fractions out of the aperture and build a mask off it. But you said you're going to remove the fractions, so please keep me updated. Thanks!

Oh I could really use this right now.

This feature was added in #453. See the ApertureMask object.
