Add an option to force metafield data when uploading a file

[jase-languasco]

I would like to see an option that forces the metafield data to be entered when uploading a file.

You can use onBeforeUpload to do something like this:

const uppy = Uppy({
  onBeforeUpload (files) {
    for (const [key, file] of Object.entries(files)) {
      if (!file.meta.caption) {
        uppyDashboard.info('File is missing caption', 'error')
        throw new Error('File is missing caption')
      }
    }
  }
})

Not perfect but the best we have at the moment; we could add a restrictions.requiredMeta: ['array', 'of', 'names'] kinda option in the future
