Update Pod version

[josh-byster]

It looks like the changes for Swift 4 compatibility have been merged in a PR, but right now running pod install will result in version 0.1.8 being installed, which doesn't have the Swift 4 compatibility.

Yes, CocoaPods is still not updated. Also in the code they still need to replace the following line:
Replace 'kCAEmitterLayerLine' with 'CAEmitterLayerEmitterShape.line'

Unfortunately, this library has not been updated for a long time and does not work after swift 4.2.
If you get an error and cannot use this library, you can visit it.
