[1/4] d(・ω・d) Collecting crate metadata

rust-lang/rust#109807
CosmWasm/cosmwasm#1727
应该是1.70+的工具链生成的wasm二进制带了mvp以外的opcode

可以尝试按装下面我修改后的cargo-liquid工具，然后再cargo liquid build试试

cargo install --git https://github.com/bxq2011hust/cargo-liquid --branch main --force

我的环境是 ubuntu 22.04 server LTS，这个仓库的Binaryen wasm-opt 不带--signext-lowering， 可以从binaryen下载
还有就是修改下template下的rust-toolchain.toml ，内容还是channel = "nightly-2023-01-03"🙂
