MacOS Installation (Monterey 12.1)

This installs several dependencies then downloads and extracts both wasi-sdk and Contract Lab. wasi-sdk provides clang and other tools and provides the C and C++ runtime libraries built for WASM. Contract Lab provides libraries and tools for working with eosio.

For convenience, consider adding the environment variables below to ~/.zshrc or whatever is appropriate for the shell you use.
