Adds handling for content in beacon network

[acolytec3]

Adds storing and retrieving of Beacon network content from local storage as well as a partial implementation of the SENDFINDCONTENT flow. This currently only handles the case where the content is delivered via uTP stream.

Overall, LGTM!

I think it's worth Typescript engineering something around the content types as we start to add more networks, but that's more about style than function.

:+1 to merge this and then work on setting up new tests

Agreed. Probably some sort of nested enum if that exists but haven't gotten that far yet.
