✨ Extend original package with more connectivity util functions

[claired4l]

Adding following functions to communicate between react-native app and Android app:

• void sendGenuineMessage(String messagePath, Callback replyCb, Callback errCb);
• void getCapableAndReachableNodes(String capability, Callback replyCb, Callback errCb);
• void getNonCapableAndReachableNodes(String capability, Callback replyCb, Callback errCb);
• void openRemoteURI(String uri, String nodeId, Callback replyCb, Callback errCb);

See README for more details

Sorry. I decided to not merge the PR, because I'm focusing our efforts on other priorities.

My plan is to follow as close as possible to the API react-native-watch-connectivity.

There is a list of issues and feature requests in the issue tracker.

I believe your APIs are a nice improvement, but they are best kept in a separate library.

We don't know how many users would benefit from these more advanced features, for this reason I'll prioritize other features for now but may come back to this PR and take inspiration in the future to add improvements to the library.

OpenSource is something we do in our free time. For this reason we need to be modest in our goal and avoid taking to much tech debt by adding a lot of complexity ti the library and maintenance.

So features that are not requested by the community may not get merged.

Thanks a lot
