Replace box/spout with openspout/openspout

Hi,

The box/spout project is no longer maintained.
https://github.com/box/spout

I would suggest to use this one instead.

https://github.com/openspout/openspout

Feel free to send a PR for this! If the tests still pass, I'd certainly consider merging it in.
