Don't install flashing scripts
These were split out to a separate repo. Keep the scripts around but don't install them in the package until all the docs got updated.
This is a stripped down version of !223 (merged) that does the packaging split but keeps the flashing scripts in place until docs are fixed to avoid confusion. We can then drop the scripts later (but don't make any more changes on those here).
