roclang release v0.2.0

roclang 0.2.0

Enhancements:

• Enable selection of multiple parameters when using type = "param", in accordance with the update from roxygen2 > 7.1.2 that co-documented parameters should be selected in a whole set when extracting their shared documentation. However, selecting multiple independently documented parameters using type = "param" is still not allowed, since the documentation to diffuse should keep to a single entry per call. To diffuse documentation from multiple independently documented parameters, please call the function on each of them.

• Add check on whether the extracted documentation entry is invalid (NA_character_) or multiple. These two cases will now result in error, since in most cases such results are not expected. The documentation entry can be multiple if selecting multiple independently documented parameters using type = "param" (not allowed).

• Keep backward compatibility with roxygen2 <= 7.1.2 while accommodating to the changes (tested under roxygen2 = 7.1.1).
