Add package version to packaged js #86
Description
Currently there is no way to check what version is available for CDN based distribution:
https://unpkg.com/web3data-js/dist/web3data.min.js
The version of each built file should be added along the methods as a way to check package version.
Syntax Idea:
const version = Web3Data.version
console.log(version) // 0.7.3
