Updated library example to .net Standard v2.1.0

Updated the library example code to use the new version v2.1.0 of the library with support for .net standard.

Added Library Example

Added an example project using my new Nuget Library : https://www.nuget.org/packages/ReadingBusesAPI/

Reading Buses API Example

I have since added a new example using the Reading Buses API instead of the old Reading Open Data API. The Reading Buses API is significantly easier to use and any projects should be migrated over to it.

Initial Public Release

This release contains the code used to retrieve bus services in Reading, their routes and stops and then the live times at a selected stop. To run the code you will need Visual Studio and your own API key as described in the read me text file.
