SCIFIO link

Updating the BF SCIFIO docs to link to the SCIFIO page at LOCI so we don't need to reproduce Mark & Curtis' updates to keep this up-to-date and everyone can find the latest SCIFIO documentation etc.

N.B. Done this way rather than removing the file completely because we link to it throughout the supported formats table which is autogenerated.
