Verify that no other packages use the 'bitmap' interface.

[BerylKanali]

The bitmap vignette in AnnotationDbi package has been labelled deprecated meaning it should be phased out or removed.
https://bioconductor.org/packages/release/bioc/vignettes/AnnotationDbi/inst/doc/AnnotationDbi.pdf

Users are no longer supposed to use the 'bimaps' interface but we don't know whether other Bioconductor packages are still using it or not. We will keep the vignette around until we know for sure that all packages have migrated to the 'select' interface which is the replacement for the 'bitmap' interface.
