Support in-memory file via StringIO?

[hokster7]

The README says:

If you want to upload a file directly to Cloud Convert, pass the file object to the file argument. Make sure that the file object you are passing responds to the read method. Examples: File, Tempfile, ActionDispatch::Http::UploadedFile, etc.

Well ... I thought StringIO supports read so I would use that.

But then:

~/.rvm/gems/ruby-2.2.4/gems/httmultiparty-0.3.16/lib/httmultiparty.rb:16:in `file_to_upload_io': undefined method `path' for #<StringIO:0x007fe726b27900> (NoMethodError)

Why path?

raw input just didn't work for me.
Only file worked.
