TS100 Thermal Runaway Retune/Option to disable

[Tekz42]

Is your feature request related to a problem? Please describe.
TS100 going into thermal runaway constantly while soldering with low voltage power sources i.e. 3s LiPo. This makes soldering in the field a headache as Iron is constantly going into cooldown causing joints to be half soldered.

Describe the solution you'd like
Retune of Thermal Runaway or Option to disable Thermal Runaway.

Describe alternatives you've considered
Buy higher voltage power sources.

Additional context
N/A

I have previously reported this issue with my TS80. If you work on something that takes time to heat up and then stabilizes on some temperature, the TS80 goes into runaway mode. Please add a some test before triggering this mode: Turn down heating a bit (say 50%) and see if the temperature drops. AFAIK this should not be the case with an actual runaway, where the temperature sensing itself is broken? So it would not decrease in that case. But not sure if I understand the mechanics behind a runaway correctly.
