Refactoring related to ReactPy v2.0.0

[shawncrawley]

Description

My attempt at refactoring to align with ReactPy v2.0.0. This depends upon the refactors that were also made to reactpy-router to align with ReactPy v2.0.0 (see PR for that here).

There are a few remaining fixes/updates that I haven't been able to figure out yet. These are the related tests that fail when I run them locally:

• tests\test_app\tests/test_components.py:230 ComponentTests.test_component_use_user_data
• tests\test_app\tests/test_components.py:286 ComponentTests.test_component_use_user_data_with_default
• tests\test_app\tests/test_components.py:685 ComponentTests.test_form_basic
• tests\test_app\tests/test_components.py:779 ComponentTests.test_form_bootstrap
• tests\test_app\tests/test_components.py:817 ComponentTests.test_form_orm_model
• tests\test_app\tests/test_components.py:575 ComponentTests.test_pyscript_1_multifile

The first two are related to open discussion here. As for the rest, I still have no idea what the problem is after digging for hours.

So I actually realized that most of the pyscript code here in reactpy-django is now duplicated in reactpy core. I went through and essentially removed essentially all of the duplicate code and just reference it in reactpy. With this change, I still get the same test failing that I couldn't ever figure out why before, but now I'm actually getting a py-script error rather than silent/masked failures. Here is that error:

I haven't pushed these code updates since I haven't solved this bug and wanted some feedback on it. Also, I wanted to make sure that purging most of the pyscript code from reactpy-django and instead referencing it in reactpy core is desired. Let me know your thoughts on this. I'm happy to push my code updates if desired.
