Lowercase `qty` doesn't work as an `explode` default, contrary to docs

First of all, Squib is a wonderful tool. Thanks much for your hard work.

I ran into an issue where the qty column in my deck's CSV was being ignored, despite documentation claiming it's the default for explode: https://squib.readthedocs.io/en/v0.14.0/dsl/csv.html?highlight=qty

I then checked the examples and saw that the Q was capitalized. That fixed the problem. However, the docs ought to reflect that, or Squib ought to tolerate lowercase here.

Good catch! I’ll fix the docs. In general all parameters are lower case.

And thank you for the kind words!

Thanks, and you're very welcome!
