Update to use qtpy imports

[goanpeca]

Hello team!

The plugin documentation for napari has a set of best practices for developers, which includes a clause recommending not to depend directly on PyQt5 or PySide2 to allow end-users to choose their bindings freely. More details here.

The files using PyQt5 instead of qtpy are listed here ->

napari-organoid-counter/napari_organoid_counter/_widget.py

Line 9 in 224eff9

from PyQt5.QtCore import Qt

Also I suggest you do not use the * import. That is generally not recommended

Some options might include changing this code

from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import *

To

from qtpy.QtCore import Qt
from qtpy.QtWidgets import QWidget   # and explicitely list everything that is needed

Or to

from qtpy import QtCore
from qtpy import QtWidgets

# And then use it like

class OrganoidCounterWidget(QtWidgets.QWidget):

I favor option 1 as it is more explicit in what needs to be imported for a given module.

Is there a reason you need PyQt5 explicitly? Could these imports be updated to use qtpy for the next release?

If you have questions, or need some help, let me know :)

Thanks! 🚀
