Homebrew release of Multihash Tool

This is the unofficial "Homebrew" version of the multihash tool command, which can be easily installed in non-Golang environments.

Its purpose is to check multi-hash values without the need to use or install IPFS.

# macOS and Linux (AMD64, ARM64/M1)
brew install KEINOS/apps/multihash

Same as "go-multihash", but with the following differences:

• Version display.
• Unit tested.
• golangci-lint checked.
• golint checked.

Usage
