add biocViews to DESCRIPTION

[slowkow]

Bioconductor dependencies won't be automatically installed without additional annotations.

One way to indicate that some of the dependencies might come from Bioconductor is by adding the string biocViews: to the DESCRIPTION file.

This code in remotes detects the string biocViews::

A second way to do it is to list each Bioconductor dependency twice. First, list it in Depends:, Imports:, or Suggests:. And then list it again a second time in Remotes:. This is described here:
