Enhancement to x-fmt/276 #44

Hi, I'd like to propose to add "SIK" as an additional external signature to x-fmt/276.

In our case, we had a submission which contained pairs of files in the same directory which only differed in the suffix (e.g. file1.txt, file1.SIK) and sometimes the file's contents had some slight variations. After running DROID the TXT and SIK file were identified as x-fmt/276. Investigations^1 revealed, that the SIK extension stands for "SIcherheitsKopie" (ger. for Backup copy) and is a temporary file generated by Word. The files do only differ in the external signature, the internal signature is the same. Could be that the SIK extension was only used in the german speaking market, as I only found german sources which do name the SIK extension.
