Add a function to add Requirements to Exisiting Intune App

[Walmtech]

Thanks for such a useful tool.

Would be useful if new requirements are required to be added to an exsiitng app.

Something similar to Add-IntuneWin32AppDependency that allows you to add additonal requirements on an existing app.

Suggest Add-IntuneWin32AppRequirement that lets you use the existing
New-IntuneWin32AppRequirementRuleFile
New-IntuneWin32AppRequirementRuleRegistry
New-IntuneWin32AppRequirementRuleScript

To add an additonal requirement.
