Scaffold noah cli (#10)

* CLI skeleton * noah CLI: send flags * add cypher.go file * fix .PHONY * add password_hash in state.json * encode public key using common pkg * use common.DecodeUrl * remove cli.Exit calls * redeem command: make --amount flag optional only if --force is not set * remove validateURL func * chmod +x scripts/build-noah * Update cmd/noah/redeem.go Co-authored-by: João Bordalo <bordalix@users.noreply.github.com> * Update cmd/noah/redeem.go Co-authored-by: João Bordalo <bordalix@users.noreply.github.com> * Update cmd/noah/init.go Co-authored-by: João Bordalo <bordalix@users.noreply.github.com> * Update cmd/noah/main.go Co-authored-by: João Bordalo <bordalix@users.noreply.github.com> * Update cmd/noah/send.go Co-authored-by: João Bordalo <bordalix@users.noreply.github.com> * rework receive and send * Update cmd/noah/send.go Co-authored-by: João Bordalo <bordalix@users.noreply.github.com> * Update cmd/noah/send.go Co-authored-by: João Bordalo <bordalix@users.noreply.github.com> * Update cmd/noah/redeem.go Co-authored-by: João Bordalo <bordalix@users.noreply.github.com> * receive command: return ark address --------- Co-authored-by: bordalix <joao.bordalo@gmail.com> Co-authored-by: João Bordalo <bordalix@users.noreply.github.com>
