ios 11 crash

I find that when the source image's width bigger than height just 1 pixel, then after called cropping, the result is same to source image. so, image's width is not equal to the height. we should use min(width, height) as radius. Can you fix it?

Hey, just tried to reproduce the failing test and yes! It's failing.

Given image: (W:151, H:150), and the test is already exist:

Nuke/Tests/NukeTests/ImageProcessorsTests/CircleTests.swift

Line 15 in f854af8

func _testThatImageIsCroppedToSquareAutomatically() throws {

Failing with:
testThatImageIsCroppedToSquareAutomatically(): XCTAssertEqual failed: ("(151.0, 150.0)") is not equal to ("(150.0, 150.0)")

I'm working on it and will make a PR.
