Update names.dat

Description

Trying to add the name of Calvera's supernova remnant. I'm not sure if @alex-w added all of the SNRs and candidates to catalog.dat (I didn't verify by ctrl-f-ing catalog.txt), but this one is an especially unusual SNR because of how far off-plane it is.
Source is the discovery paper or could use a later paper on the target.

Thanks for contribution. By the fact I've not added SNR candidates into the joined catalog of DSO. Should we add SNR candidates into DSO catalog for version 26.1?

Where are they stored now?

IIRC there is a separate color for SNR candidates, so they should also be in the catalog.

While the Calvera SNR is officially a candidate, there's been multiple papers that support it as a SNR. Also, the guy behind the catalog has retired and IDK if there will be future updates. Can the Calvera be added to SNRs? I would also appreciate adding SNR candidates to Stellarium for 26.1.

Is it possible to provide a machine-readable catalog for SNR candidates, similar to SNR catalog?
