Set the module to be system agnostic

Linked to this issue : PowershellFrameworkCollective/psframework#191
Here is the documentation saying / and \ are agnotic with cmdlets : https://docs.microsoft.com/en-us/powershell/scripting/whats-new/what-s-new-in-powershell-core-60?view=powershell-6#filesystem

Hence why I did not chance all the calls to "Path"
But it seems to not be the case for .NET Methods (or at least some of them)
