Adding MSIX to Application_LOB_Add.ps1

[NEllis280]

Added functions to the Application_LOB_Add.ps1 in order to include MSIX type LOB apps.

Get-MSIXManifest retrieves the MSIX manifest from the bundled MSIX package in order to populate data about the application.

Get-MSIXPublisherId gets the publisher ID hash from the publisher name retrieved from the appx manifest.

Get-MSIXFileInformation populates values from the retrieved appx manifest for the following: DisplayName, Description, Publisher, IdentityVersion, PublisherHash (passed in from Get-MSIXPublisherID), and IdentityName

Get-MSIXAppBody generates the body for the post request.

Upload-MSIXLob performs the addition of the MSIX LOB app to intune using the new functions, as well as the functions that already exist in the codebase.

Please note that I have attempted to write the new functions adhering as closely to the style of the existing codebase.
