v3.0.0-rc.0

• Changed WeakMap for private field (require node 12)
• Switch to ESM
• blob.stream() return a subset of whatwg stream which is the async iterable (it no longer return a node stream - now it returns a AsyncGenerator)
  • If you really want to have a node stream then you would have to use Readable.from(blob.stream())
• Reduced the dependency of Buffer by changing to global TextEncoder/Decoder (require node 11)
• Disabled xo for index.js since it could not understand private fields (#)
• No longer transform the type to lowercase (https://github.com/w3c/FileAPI/issues/43) This is more loose than strict, keys should be lowercased, but values should not? It would require a more proper mime type parser - so I just made it loose.
• index.js can now be imported by browser & deno from a CDN since it no longer depends on any core node features and dose not bundle anything to commonjs
• used a more direct approach to convert blob to string that don't involve allocating hole arrayBuffer that would take up twice as much RAM while converting it to a string
• changed node engine to just be >14+ in package.json
