Can't delete paths anymore

[reuvenharrison]

Hi,
Before #882 I could delete a path like this:

func filterPathsByExtensionInternal(paths *openapi3.Paths, r *regexp.Regexp) {
	for path, pathItem := range paths.Map() {
		for extension := range pathItem.Extensions {
			if r.MatchString(extension) {
				delete(paths.Map(), path)
				break
			}
		}
	}
}

After the PR, Map() returns a copy rather than the original paths map which makes it impossible to delete paths.
I suggest to add a Delete function in maps.sh similar to the Set function.
I'm happy to create the PR if this makes sense.

Ah sorry about that. I did mean Map() to return a copy (in preparation of the orderedmaps PR).
You're right the solution here is as you describe.

Please send a PR :)
