Your parser is off to a good start: you nailed the general idea of good API design. In other words, it's easy to use, which is immediately appealing. For other things, I think there's been great feedback in the rest of these comments.
(By the way, Papa Parse only uses jQuery for convenience in interacting with the DOM for things like file input elements. The core parser, including the file streamer, is vanilla Javascript.)
