Bug#993156: nvidia-driver: recommend libnvidia-encode1

[mooff]

Package: nvidia-driver
Version: 470.57.02-2
Severity: normal
X-Debbugs-Cc: mooff at awful.cooking

Dear Maintainer,

I think it would be appropriate to add libnvidia-encode1 to recommends
for nvidia-driver.

It would help to make this common GPU feature part of the standard
install - and might help to offer motivation for the obs-studio and
ffmpeg packages to support the NVenc encoder out of the box in
Debian.

Thanks a lot, I think 'apt install nvidia-driver' is the cleanest
experience I've had installing a proprietary driver on any OS.
