Build is failing due to SwiftLint rule 'shorthand_operator'

[mmysliwiec]

The latest version 7.0.0 is failing to build with Carthage due to SwiftLint 0.43.1 rule 'shorthand_operator'. File SKZoomingScrollView.swift at line 154 have this code:

maxScale = maxScale / scale

And it's causing the SwiftLint to generate error:
Shorthand Operator Violation: Prefer shorthand operators (+=, -=, *=, /=) over doing the operation and assigning. (shorthand_operator)

I can see three possible solutions:

1. Fix the source code to maxScale /= scale (I've tested it and this fix the issue)
2. Add comment to remove this particular rule for this line // swiftlint:disable:next shorthand_operator
3. Exclude the shorthand_operator rule with .swiftlint.yml configuration file.

Which one do you prefer? I can make a PR for any of proposed solutions.
