Add Podspec for Cocoapods

TODO (Before merge):
- [ ] Update version in Podspec if necessary
- [ ] Verify/Update deployment targets (what about tvOS? watchOS?)

TODO (After merge):
- [ ] Add a new tag for initial release (Matching Podspec version)
- [ ] `pod spec lint` to verify it works
- [ ] `pod trunk push` to publish to cocoapods (Will need to `pod trunk register` if you've never published to cocoapods before)
