parallel upload of chunks

It's a good idea, we've gone down this path before! Unfortunately our primary backend (GCS) doesn't support uploading chunks concurrently so we ended up abandoning it. Still open to this for other backends, though!

I think you're on the right track in terms of configuration:

• Should not be the default behavior
• Need to be able to configure the number of concurrent chunks

Also just a heads up, we ended up doing quite a bit of experimentation at Mux over performance for large files like this. One of the big reasons why we ended up with our adaptive chunk size approach is because (up to a point), the fewer chunks, the faster the upload in total. Might want to experiment on that side of things as well.

My intial test with adaptive chunk size is promising. I will see if that works and get back to you if we decide to experiment with concurrent chunks.
