Given a transaction or script in Cadence generate FLIX format 1.0.0

• [x] Use cadence comment header for all properties
• [x] Fill in Dependences, support multiple ways smart contracts can include dependencies
  • import contract with address
  • new import syntax that relies on flow.json
  • old import syntax that uses placeholder)
• [x] Fill in Parameters
• [x] Fill in all Messages and support languages
• [x] Build hashes. See, generating FLIX has to know about pinning hash (See in fcl) https://github.com/onflow/fcl-js/blob/master/packages/fcl/src/interaction-template-utils/generate-dependency-pin.js
