Follow-up to #254. The Atom tables on List of Intel Atom processors have only a "Cores" column, and the import copied the core count into threads. That's right for the Silvermont, Goldmont and Tremont families, which have no Hyper-Threading. It halves the thread count for the Bonnell/Saltwell families, whose sections on the same page say every model supports Hyper-Threading.

Family Records Change
Tunnel Creek (E6xx) 8 1C/1T → 1C/2T
Stellarton (E6x5C) 6 1C/1T → 1C/2T
Lincroft (Z650) 1 1C/1T → 1C/2T
Centerton (S1220, S1240) 2 2C/2T → 2C/4T
Briarwood (S1269, S1279, S1289) 3 2C/2T → 2C/4T
Cloverview (Z2520, Z2560, Z2580) 3 2C/2T → 2C/4T

Only threads changes. Root-cause parser fix: GetTechAPI/TechEngine#91 (a bare core count now leaves threads unknown instead of guessing).

Closes #1

The Atom list tables only give a core count and the import copied it into
threads. The same page states every model in these six families supports
Hyper-Threading, so threads = 2 x cores.
