chore: update example to RN0.61.5

[Naturalclar]

There seemed to be many people who are having trouble with using this library in RN 0.61.x, as shown in #43 and #50

I've upgraded the example directory to get it working with RN 0.61.5

Checklist

• I have tested this on a device and a simulator

Aren't these methods still required as long as we continue to target iOS <10.0?

Also, maybe it is time to add the more recent, non-deprecated methods.

Regarding this line...

import RCTDeviceEventEmitter from 'react-native/Libraries/EventEmitter/RCTDeviceEventEmitter';

...this shorter version works for me (RN 61.5):

import { DeviceEventEmitter } from 'react-native'

@Entryist Thanks so much for the info 👍 updated the example to use DeviceEventEmitter
