After the addition of the rust-std-static-wasm32-wasi target, we're
able to compile the Rust programs to Wasm binaries. However, we're still
only able to handle the Wasm UDFs in the Text format, so we need a tool
to translate the .wasm files to .wat. Additionally, the .wasm files
generated by default are unnecessarily large, which can be helped
using wasm-opt and wasm-strip.
The tool for translating wasm to wat (wasm2wat), and the tool for
stripping the wasm binaries (wasm-strip) are included in the `wabt`
package, and the optimization tool (wasm-opt) is included in the
`binaryen` package. Both packages are added to install-dependencies.sh
