Safe install/uninstall #1

Safe installation and uninstallation imply that during install and uninstall, an additional function is performed that looks for package dependencies. This function controls that when a package is removed, dependencies in other packages remain intact, and unused dependencies are deleted along with the package.
It will be easier to explain with an example: Imagine that you have an aiohttp package and a pydantic package. They both have a typing-extensions dependency. If you delete one of them, all other dependencies except typing-extensions will be removed.
