## Description

To fully implement RFC-616, we need a way to get the original FITS WCS from a raw file. As proposed in that RFC, this will be a "raw_header_wcs" datasetType in the butler (gen2 and 3).

Nate Lust: can you please review this small change? The gen3 implementation isn't actually used anywhere, as I don't know how to register a new gen3 composite dataset type: if you can suggest how to get the new formatter.readRawHeaderWcs() method accessible to the gen3 butler, I would greatly appreciate it.

Sorry it has taken so long to get to this, lots of travel and such. It all looks good to me.

New post-review rebasing jenkins run: https://ci.lsst.codes/blue/organizations/jenkins/stack-os-matrix/detail/stack-os-matrix/30559/pipeline

Nate Lust: did you have any ideas about how to get the functionality accessible to gen3? I've got a method implemented-formatter.readRawHeaderWcs-but I don't know how to tell gen3 to call that for the raw_header_wcs dataset type (or whatever the new name is).

I had a quick look, I should have time tomorrow to look in depth and give you an answer.

I removed the daf_butler component from this ticket since this fix was entirely in obs_base. We will need another ticket to enable the gen3 change.
