nwztools/upgtools: rewrite keysig brute force search
The new search has two new features:
- it takes advantage of the fact that DES keys are only 56-bit long (and not 64)
- it is now multithreaded
As a proof of concept, I ran it on the A10 series firmware upgrade and was able
to find the key in a few seconds using 4 threads. The search is still limited
to ascii hex passwords (seems to work on all devices I have tried thus far).
