Buffalo Gap, IAB-ungrouped

We wrote the Meteoritical Bulletin write-up for this iron; I can’t think of anything else to add.

In short, it’s ~similar to other IAB irons, but is only closely related to Mundrabilla and Waterville, two troilite-rich irons that also have similar trace element abundances and are likely related.  If more similar irons are found, we may have a new group on our hands!
