This commit adds the new set of single funder messages from the specification. As a result, after this commit and a follow up, all of our messages will directly line up with those that are detailed within the specification. The new set of funding messages are very similar to our prior ones, aside from the main difference of the addition of several channel level constraints that give nodes control over their exposure, throughput, and other values.
