- Reduce requirements for the python build.
- Fix version number.
- Generate type hints for *.pyi files.
- Make functional for sip-build
- Reduced the unnecessary depth of the package.
NOTE: This is a breaking change for python users, where, `from PyQtAds import QtAds` is changed to `import PyQtAds as QtAds`( or simply `import PyQtAds`)
* Add dockdepth1 example
* Fix compilation (include assert.h)
* Replace dockdepth1 by dockindock
* Fix crash when dockindock example is closed. Due to code in dockindock supposed to fix memory leaks: now leaks were fixed in CDockManager (https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System/issues/307), the code from dockindock ends up deleting objects already deleted by parent.
