create stream from iterator

[calvinmetcalf]

from tc39/proposal-async-iteration#74, adds a wrapIterator method on the prototype similar to wrap, wonder if it would also make sense to add a similar static method on the constructor, maybe taking a second argument for constructor options

[calvinmetcalf]

making it static would probably be more robust against clashes but would have the problem of needing to specify objectMode, which would make sense to be off by default for a lot of cases, but not all

Readable.from([1, 2, 3]);// objectMode makes sense
Readable.from(Buffer.from([1, 2, 3])); // objectMode does not make sense
// but what about
Readable.from([buffer1, buffer2, buffer3]);// either could make sense
// same with
Readable.from('a string');// do we iterate through the characters in object more or just treat it as a string not in object mode

@calvinmetcalf how about:

const from = require('async-iter-stream').from

from(Buffer.from([1, 2, 3]))
from.obj([1, 2, 3])

It follow the same pattern of through2, and we can even publish it as its own module.
It make sense here, as it's more an "experimental module" for streams and promises.

really really good work.

yes but I was thinking of it in terms of api for bringing into node possibly which doesn't use the .obj convention
