Embed fibre client in the node API

[cmwaters]

Users should be able to use either their light node or celestia client and easily be able to interact with fibre:

• Post data
• Retrieve individual fibre blobs by commitment
• Retrieve fibre blobs and regular blobs by subscribing to a namespace or reading off an entire namespace

This should support both the blobs and the necessary proofs to prove inclusion.

I believe this should work as seamlessly as possible with the existing API, specifically Get, GetAll and Subscribe should work with namespaces with fibre (as well as non-fibre blobs)

Submit should also work with the user only needing to specify the v2 share version.
