tokenfactory custom message encoders

[discoverdefiteam]

Hi! wanted to open up this discussion and see if others would agree that it would be useful to implement the custom message encoders for the x/tokenfactory module?

Osmosis implements this feature here, and it seems like this may be useful for calling the tokenfactory in custom contracts

We are currently avoiding adding new custom bindings and rather going with stargate queries and messages you can find an example here https://github.com/jhernandezb/tokenfactory-example/blob/main/src/contract.rs
