REST: increase max msg size for REST proxy

Browse Source 
Some time ago, we modified `lncli` to accept larger responses from the
server, up to 50MB. However, we failed to update the REST proxy, which
is in a sense, a client to the regular RPC server. As a result, users
can't currently hit the `/v1/graph` endpoint, as it'll fail with an
error.

In this PR, we update the proxy's dial options to allow it to receive
larger responses from the actual gRPC server. This is only a temporary
measure however, as we'll eventually want to expose some sort of
pagination for the end client.
