    .SYNOPSIS
        Reads an entire plist file as a PowerShell object using plutil.
    .DESCRIPTION
        Uses /usr/bin/plutil to convert the plist to JSON in a single process spawn
        and returns a PSObject. Significantly faster than multiple PlistBuddy calls
        for the same file (1 process instead of N).
