Mockable Peripheral

[UnknownJoe796]

It would really help us with our testing if we could make our own implementation of Peripheral to test against.

With Peripheral being a public interface, we are so close to being able to fully mock the device we're connecting to. However, DiscoveredService is platform specific, which interferes with attempts to mock it.

I would like DiscoveredService and DiscoveredCharacteristic to be interfaces such that they can be mocked, if it is possible.

Thanks! This library is pretty awesome for our use so far!

Aw yes. Makes sense. That should be do-able. I'll try to tackle this after I get 0.35.0 release out.
