This PR adds support for computing free-free and free-bound continuum emission. It closes #23.

Additionally, this PR adds a speedup for listing ions and is especially useful when creating collections of many ions which is currently slow.

Closes #28

The free-bound calculation is now fully implemented, but does not match well at all with the equivalent calculation in CHIANTI IDL. In particular, a lot of the high-temperature emission seems to be missing. Not yet clear what the issue is. In the image below, the fiasco calculation is shown in the top panel and the IDL calculation in the bottom panel.
