Feature Request: pass file meta.data in uppy.onAdd()

[Aarbel]

Problem

I'd like to send many files in the same time but with different files metaData.
The combination of uppy.setMeta uppy.addFile doesn't wok because the upload is asynchronous, and when files finish to upload they will heritate the last uppy.setMeta configuration.

Moreover the uppy.setFileMeta method is quite impossible to use, because on uppy.addFile we can't declared an id, and there's even no way to pass data to uppy.on('file-added'

Request

Add the possibility to pass meta data directly in uppy.addFile options

Looks like you found out how it works in #2106? We should make sure it's documented that you can do addFile({ meta: {xyz} }), yes :)

@goto-bus-stop i only passed relativePath key.
Seems other custom keys don't work inside addFile({ meta: ... })

Hmm if I do

const Uppy = require('@uppy/core')
const uppy = new Uppy()
const id = uppy.addFile({
  meta: { test: 'abc' },
  data: new ArrayBuffer(8192),
})
const file = uppy.getFile(id)

I do see test: 'abc' in the resulting file. Could you share some code that shows the problem?
