        .SYNOPSIS

        return whether a Windows Event Log source is already registered

        .DESCRIPTION

        Thin wrapper around [System.Diagnostics.EventLog]::SourceExists(), extracted into its

        with a mock instead of depending on real Windows Event Log state or elevation.

        .PARAMETER Source

        the event source name to check

        .OUTPUTS

        bool

        .EXAMPLE

        Test-OnypheEventSourceExists -Source 'Use-Onyphe'

    Param (
