`--gron <key>` was motivated with a simple generation of `shlibs`-style
files. However, the same can already be done with `--gron` and using the
package index as seperator between records and keeping track of
`Provides` (compare `aur-graph`).

`--gron-raw` also allows to deal with sparse or nested AUR records, e.g.
from `pkgname.json` or `pkgbase.json`.
