0.9.8: hot parts read at their exposed pad, footprint thermal vias counted (issue 20)

adom-fields 0.9.8
- Hot parts read at their tab (issue 20).
- The bug: a part whose tab net has several pads (an exposed pad plus corner pins on GND) was read at its first pad in board order. Its rise, via count and thermal-via issue came from a corner pin, not the die pad.
- The fix: it is now read at the pad named by
hot.<ref>.tabPad, else the largest tab-net pad. Vias are counted near every tab-net pad, and a footprint's own thermal-via holes count. - On the AM/FM receiver's QFN-48: with 0.5 W in it, the exposed pad reads +15.2 °C (it read +10.4 °C at pin 7), with its 9 footprint thermal vias counted (it read 0).
