[Find Duplicates] Search scope feature

[mathprod]

Hello,

Could it be possible to add the search scope feature, similar to the one in Quality Check, to the Find Duplicates plugin. In case of large libraries, trying to run the binary compare on the whole library takes too much time. Having the option to perform this comparison only on the selected files could be really helpful and more practical in such cases.

Anyways, thanks for all the very useful Calibre plugins!
