Bug#970842: opencv: please move away from libdc1394-22-dev to libdc1394-dev

[Gianfranco Costamagna]

Source: opencv
Version: 4.2.0+dfsg-6
Severity: important
tags: patch

Hello, please do the switch, the old libdc1394-22 source packages will be removed,
and reverse-dependencies should move to the new libdc1394 package.

The old libdc1394-22-dev is now provided by the new source package as transitional package,
but I presume it will go away eventually, so please adapt to the new versionless dev scheme

thanks

Gianfranco
