📏 Report binary size on PR

[bdeneux]

📝 Description

Given that the size of a smart contract is very important and that it has a very strong impact on transaction costs, it seemed to me necessary to add a small action allowing to report the evolution of the size of each smart contract binary wasm.

🛠 Tool

The tool used here is size-limit-action in addition to size-limit javascript tool. It's the only github action always maintained that allowing report file size evolution into a PR comment. Cargo-bloat also exist but is not compatible with wasm target.

A limitation can be set for each file and make the PR failed if the file size exceed the limit.

🐛 Issues

• package.json 😭😭, since size-limit is a JS tool, to make this action work, I need to add a package.json file. So to avoid pollute rust with JS stuff, I've add the package.json file setting into the GitHub action.
• Another issue is that size-limit needs a configuration file to set which file it should analyse. But for the first PR, the config file doesn't exist into the main branch, so the action failed (for comparaison with the main branch of course, size-limit need to build on it). A temporary solution is to add the configuration file into the package.json into the GitHub action, it's working but I prefer set the configuration into a specific file .size-limit. Since package.json size-limit configuration is priority, we need after this PR merged, remove the configuration from package.json.

It's working ! Just by adding a RUSTFLAGS at the compilation time (like cosmwasm documentation said), the wasm binary decrease by 90% 😍.

Great initiative! ❤️

Some remarks we can discuss.

And just a point of detail about this commit: feat: add binary size action. It should be prefixed with "ci:" like you did for the others. 😛

About this commit, I've removed it instead of rename since it was a try of another GitHub action ☺️

That's a very relevant idea, thank you 👍 .

I'll have some little suggestions though
