Fix Python 3.10 compatibility

[awsr]

Force some values to int in order to prevent TypeError caused by changes to Python 3.10. (Most likely caused by python/cpython#82180)

Do you have the build file for this? The current build file I have doesn't work with this branch

[awsr]

I don't have a build file because I didn't even notice the main.spec file in the release assets until just now. I've just been running main.py directly from a batch file.
Is it giving a specific error or does it just not work with other branches?

[awsr]

I have also considered including the following addition to README.md before the "System Requirements" section to remind people to get the correct version of tesserocr if developing on Windows:

#### For Developers on Windows
*Before installing the requirements*, you must download a [pre-compiled build of tesserocr](https://github.com/simonflueckiger/tesserocr-windows_build/releases) and install it: `pip install <package_name>.whl`

I don't think this is an issue on tesseract. It might be due to torch which only added 3.10 support last year

Merging this on a dev branch, since I can't build the app with python 3.10
