Capture the installed packages for updates only when required

[ManuInNZ]

Description of the new feature/enhancement

In a nutshell a similar mechanism to cup all -y from Chocolatey.
At this stage if I define a baseline config with a list of packages and rerun the script, it forces a reinstall of everything.

As a user when I use winget install mypackage the system should not download the whole package is already installed (unless I force).
As a user when I use winget install mypackage the system should propose a new version upgrade if available (unless I specify a version).

Proposed technical implementation details (optional)

Capture the currently installed package, e.g. manifest copy, to compare to the install request for comparison of the locally stored version if existing.

Hey @ManuInNZ, thanks for reporting this request. It seems to overlap a lot with already existing issues though:

• List installed Apps #119
• Support for apps installed outside of the Package manager #153
• Already installed app are not detected #216
• Check if Package installed #291

So consider closing this issue and adding your feedback to one of the other issues instead :-)
