Add more concise examples to README when browser support improves #5
Description
Currently the examples in the README are a little verbose, because I want them to actually run everywhere.
It would be nice to use for await to print output rather than a custom WritableStream, but Safari doesn't currently support that.
It would also be nice to use ReadableStream.from to create streams rather than a custom ReadableStream, but both Chrome and Safari do not support that.
