* Add rpc_methods

* Adjust interface tests

* Add account_nextIndex & contracts_call, filter

* Rework AbstractArray includes with some

* Adjust tests

* Ordering

* Correct definitions (pull in from methods)

* Be agressive on filtering, regardless of isOptional

* async/await in filterRpcMethods

* map Text[] -> string[]

* Correct naming for account_nextIndex

* Remove/don't remove rpc_methods as applicable

* Cleanup method handling errors
