Added a filter to the list of models

[temaps]

The list of models is always very long and it is difficult to find the right one. Added a filter field that helps you select only the necessary models from the list.

Looks much better than current filter, which you should know how to turn on and which finds from the beginning of the model only

In general looks good, but I saw some issues:

1. when running the program, I get 2 exceptions:

Traceback (most recent call last):
  File "/usr/local/share/system-config-printer/newprinter.py", line 3875, in on_tvNPMakes_cursor_changed
    self.fillModelList()
    ~~~~~~~~~~~~~~~~~~^^
  File "/usr/local/share/system-config-printer/newprinter.py", line 3916, in fillModelList
    filter_path = self.models_filter.convert_child_iter_to_path(iter)
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'TreeModelFilter' object has no attribute 'convert_child_iter_to_path'. Did you mean: 'convert_child_iter_to_iter'?
Caught non-fatal exception.  Traceback:

The above happened when I opened the driver dialog during printer adding process.

File "/usr/local/share/system-config-printer/newprinter.py", line 1369, in _handlePrinterInstallationMode
    name = model.get(iter, 0)[0]
           ~~~~~~~~~^^^^^^^^^
File "/usr/lib64/python3.14/site-packages/gi/overrides/Gtk.py", line 1010, in get
    values.append(self.get_value(treeiter, col))
                  ~~~~~~~~~~~~~~^^^^^^^^^^^^^^^
TypeError: Argument 1 does not allow None as a value

This one I cannot reproduce, but it happened somewhere when I either went back to Manufacturers window, or when I was switching from Brother to HP.

Would you mind looking into them?

Thank you!

1. when running the program, I get 2 exceptions:

Yes, I was wrong... In the final version, I did not replace the method, which I copied from my old project, where I defined this method... I will fix everything now and add a check.

I fixed and did a force push.
