SigScanner non-Dalamud interference

[slotthhy]

If another program manages to hook into XIV before Dalamud can create its module copy, any locations that were hooked by the other program will be unavailable. This occurs with Deucalion/ACT. See https://github.com/ff14wed/deucalion/issues/23

The solution here would be not to create an in-memory copy of the module, but to read a copy of the module from disk for this use as outlined in the issue above. I already use a custom SigScanner in my plugin that is affected by this issue, I will work on a solution here and then I can port it to Dalamud if deemed necessary.
