[cnpryer]

• Huak toolchain #718

As a first pass Huak's toolchain implements the following CI

huak toolchain update <tool>           # Update the current toolchain tools
huak toolchain install <channel>       # Install a toolchain via its channel
huak toolchain uninstall <channel>     # Uninstall a toolchain via its channel
huak toolchain add <tool>              # Add a tool to the current toolchain
huak toolchain remove <tool>           # Remove a tool from the current toolchain
huak toolchain run <tool>              # Run a tool installed to the current toolchain.
huak toolchain info                    # Display the current toolchain's information
huak toolchain list                    # Display available toolchains

settings.toml and use are not fleshed out yet.

huak toolchain use <channel>           # Use a toolchain via its channel
