Standardize language of "Condense Sheet"

When describing the add-on, you refer to this as condensing a sheet, combining data, and generating new sheets of data. Each of these invokes a different understanding (in me at least). I’d recommend choosing one set of terms and using that consistently. It’s okay if it’s a bit redundant.

Seeing this difference between the post-install tip, the menu item label, and how it’s discussed/presented in the sidebar and add-on name.
