Draft PR: Support for IDA 9.0 API Changes

[xuing]

This Draft PR updates the script to work with IDA 9.0. The changes ensure compatibility with IDA 9.0.

Compatibility with older versions is untested.

Unfortunately it doesn't work. I got an error:

I have provided a new patch. The generated script does not produce any errors on my 9.0 RC1. Could you help me check whether it works properly on 9.1?
