function SetModuleContent {
<#
.SYNOPSIS
A wrapper for Set-Content that copies lists of files
.DESCRIPTION
The implementation here is strongly dependent on Build-Module doing the right thing
Build-Module can optionally pass a PREFIX or SUFFIX, but otherwise only passes files
Because of that, SetModuleContent doesn't test for that
The goal here is to pretend this is a pipeline, for the sake of memory and file IO
