analysis.py need pango-1.0-0

Hi,

On a Raspberry Pi OS Lite installation, in headless mode, the report is not generated because analysis.py dies. By executing the script by hand we see that the error comes from a missing lib:

tinycheck:~$ sudo /usr/bin/python3 /usr/share/tinycheck/analysis/analysis.py -f /tmp/BE6E0A7A

OSError: cannot load library 'pango-1.0-0': pango-1.0-0: cannot open shared object file: No such file or directory.  Additionally, ctypes.util.find_library() did not manage to locate a library called 'pango-1.0-0'

The libpango1.0-0 package and its dependencies should be installed by install.sh.

That's not the point. Installing libpango1.0-0 fixes the problem. I just suggest including this package (and its dependencies) in the installation process.
