[Feature]: Extension manager with dependencies validation

[RGX650]

Feature description

PURPOSE:

• prevent breaking SDNEXT installation
• avoid & trace dependency incompatibility issues
• giving better oversight for SDNEXT devs and extension devs
• could possibly automatically sort and identify SDNEXT dev issues from extensions related issues ;)

ADDITIONAL FEATURES:

• Installed dependencies history: Save/Autosave/Recover SDNEXT dependencies vs Installed extensions dependencies
• Installed extensions history: Save/Autosave/Recover Installed extensions
• Ability to define extensions installation order...? (Maybe usefull regarding circular dependencies or to auto sync deps versions, idk...)
• Ability to share Comments/Flags/Warning/Comments between SDNEXT users regarding "inter-extentions" compatibility

EXTRAS?:

• Extention relation + compatibility graph visualization...?
• Ability to use local wheels
• Ability to use an existing venv upon first SDNEXT installation
• Ability to use a duplicated venv as sandbox (for devs)

NOTES (regarding the currently implementation i am trying to achieve or managed to do so far...):

• leverage Python Poetry for package dependency management + debug-resolving
  (package mode = false , poetry debug resolve , poetry install --no-root --only main)
• VCS control through a dedicated local git repo to host the pyproject.toml and exported requirements.txt files (Poetry + githooks)
• Poetry + pypiserver with specific configuration to use local wheels if available
• configurate specific local repo (for local wheels)
• add supplemental/explicit sources and configurate pypi extra-index-urls

PS: How can i use a premade venv to install SDNEXT? Is it as simple as:

• git clone SDNEXT
• create custom venv in .../automatic/
• Edit webuit.bat with: set VENV_DIR= .../automatic/venv
• activate created custom venv
• run webui.bat
