Release version 1.0

[sizmailov]

⚠️ Project was rewritten from scratch for 1.x. This allowed me to address some long-standing issues, but I might accidentally brake behaviour you relied on.

Changes:

• Updated CLI interface, some options were removed, please see pybind11-stubgen --help for details
• Replaced regex-based signature parsing with more robust procedure which enables to produce partially degraded signatures
• Added type parsing/replacing, including deeply annotated types
• Support implicit imports required for static analysis
• Add introspection of pure python functions
• Support python 3.10+ only (temporarily)
• Improved structure of test binary pybind module
