qgis-providers depends on libcharls2

[Kyler Laird]

Setting up qgis-providers (3.10.14+dfsg-1ubuntu2) ...
/usr/lib/qgis/crssync: error while loading shared libraries: libcharls.so.2: cannot open shared object file: No such file or directory

Installing libcharls solved the problem.

# lsb_release -rd
Description: Ubuntu 20.10
Release: 20.10

# apt-cache policy qgis-providers

I expected installation to work.

Instead, it failed.
