new save,when landing aquilo.

Error while running event aquilo-thermometer::on_player_changed_surface (ID 54)
LuaEntityPrototype doesn't contain key heating_energy.
stack traceback:
[C]: in function 'index'
__aquilo-thermometer/control.lua:12: in function 'calculate_heating_requirements'
aquilo-thermometer/control.lua:54: in function <aquilo-thermometer/control.lua:23>

got same error, fixed after trying latest experimental factorio beta 2.0.21

Yeah this requires changes introduced in 2.0.21. I should've specified the dependencies to reflect that.
