Allow Custom RDPWrap.ini

[Orski174]

Sometimes it takes a while for the github hosted rdpwrap.ini to be updated, which renders Duo unusable.

One can simply use RDPWrapOffsetFinder to add the missing versions to rdpwrap.ini, but Duo always pulls and checks from the hosted version instead of the local one, overwriting it with the github version.

I suggest a simple toggle to check local before pulling.

Thanks for this amazing service!

Never mind, I should've checked if I was on latest first :)
