* create channel now responds correctly given various parameters
* insert channel now errors out properly with ? syntax
* new uses added to align with sql types
Generally more explicit behavior is provided
*NOTE: if this call succeeds then we have fully authenticated and subsequent calls should have acccess to "secret" in the serialized params structure, thus unwraps should be fine as they'll be proven via informal induction
InviteRow now has some utilities built into it to help with translating values from various types needed throughout the codebase
+from_tuple -> because mysql is used to grab tuples before structs
+as_json_str -> because we respond primarily with json payloads
list_channels is considered a main entry point from the dispather and thus handles errors itself
