Very Minor Bugfix

Did some minor cleanup of the code, and noticed that Iris doesn't seem to like one of the formatting issues, so this cleanup is technically a bugfix too. 128 blocks should now appear properly on the range slider (as opposed to 128.0), and in the correct place.

First Working Version

First release, woo!

This release has support for varying range and zero-point, depth map and true distance mode, and optional inverted output.
