Issue: Support Swift's `Set` as a JSON type
**Is your feature request related to a problem? Please describe.**
`track(name: String, properties: [String: Any]? = nil)` will crash if one of the `Any` is a Swift `Set`. It will _not_ crash if that same property is an `Array`.

**Describe the solution you'd like**
Because to JSON, `Array` and `Set` are identical, it would be nice if Segment's `JSON` type could encode `Set` without crashing

**Describe alternatives you've considered**
At this point, we just ensure we're always sending an `Array`

**Additional context**
N/A
Pull request description: - Fixes #198 .
