Clear the two standing R CMD check NOTEs

Import the .data and .env pronouns from rlang, which code used unqualified,
and move sf from Imports to Suggests: no R code calls it, and cd_crop() only
checks inherits(aoi, "sf") before terra::vect(), which loads sf itself. Tests
that read their AOI with sf::st_read() now skip without sf.

Fixes #111
