init-network should be able to optionally bundle wasm files along with the network config files

[sug0]

Currently, init-network generates a ${chain_id}.tar.gz file containing network config toml files and a wasm checksums json file. It should also (optionally) contain the wasm files pointed to by the checksums file.

Most importantly, we should check the WASM hashes against the expected ones when starting the node.

#3119 is sufficient for the time being.

shouldn't we include the wasms in the chain tar.gz? and remove the download functionality from the ledger? Otherwise we have to host infrastructure

I don't think so, we can just upload the WASMs to a separate repository on GitHub and use the raw download URLs?

Maybe that's more difficult than including the WASMs in .tar.gz though?
