📚 Research automated gas testing

📚 Documentation

Research and document how automated gas testing works or could work for this repo. Implement it if it's a small change, otherwise document findings and/or create a new task after specifying how this would work.

Was doing some research and found CosmWasm/cosmwasm#1667, maybe this is something we can use to at least get insight into gas consumption?

Also found https://github.com/de-husk/cosm-orc, but not sure how good/useful this is.

Had to think of this again as it would be useful to verify the changes for #83

Gas profiling requires an end-to-end testing environment (i.e. contract calls must be ran against a real node), so gas will be profiled in end-to-end tests defined in task https://github.com/sedaprotocol/seda-internal/issues/63
