Support complex types when using clients

[moul]

Context

Clients only support passing and receiving primitive types.
Returned value is hard to parse.

We need to find a solution to support rich types. The current best approach is potentially to generate protobuf files, cue files, amino files dynamically.

Examples of clients

• gnokey: https://github.com/gnolang/gno/tree/master/gno.land/cmd/gnokey
• gnofaucet: https://github.com/gnolang/gno/tree/master/gno.land/cmd/gnofaucet
• gnoweb: https://github.com/gnolang/gno/tree/master/gno.land/cmd/gnoweb
• adena-wallet: https://github.com/onbloc/adena-wallet
• gnoblog-cli: https://github.com/gnolang/blog/tree/main/gnoblog-cli

Needed by

• https://github.com/gnolang/gno-js-client
• Teritori, returning complex types

what about making a gnob? :) (amino)

could probably keep the same specification, but with the possibility of changing it based on how gno and its primitives evolve

[thehowl]

This is partly achieved with gnokey maketx run.
