hl_cairo_viewer.f90 example: crashes when the Add window is cancelled then called again

Describe the bug
At start, if we click on the "Cancel" button of the Add window, then call it again ("Add files" button) and choose a file, the application is crashing:

At line 146 of file gtk-fortran/examples/hl_cairo_viewer.f90
Fortran runtime error: Allocatable argument 'file_list' is not allocated

Error termination. Backtrace:
#0  0x7fbc4b023ad0 in ???
#1  0x7fbc4b024649 in ???
#2  0x7fbc4b024c46 in ???
#3  0x5629beb14518 in add_files
        at gtk-fortran/examples/hl_cairo_viewer.f90:146

It does occur only at start. Not if an image was already selected.

Your system:

OS version: Ubuntu 22.10 64 bits
