[Feature] Support peripheral XCI metadata files

[monyarm]

With the advent of the Mig Switch Dumper, I think oxyromon should also support the peripheral files that the dumper creates, as it doesn't just dump ROM.xci, it also does ROM (Card ID Set).bin, ROM (Card UID).bin, ROM (Certificate).bin ROM (Initial Data).bin.
So it would be great if when it renamed files oxyromon would also catch those files, and rename them too.
