Improvements to Predheat

What's Changed

Predheat now considers the min and max power values as the output power of your system and not the input power as previously. This means a 7kw heat pump should have a max power of 7000.

Predheat now accepts delta_correction, gas_efficiency and heat_pump_efficiency values in multiples of 1 degree. If there are gaps e.g. data in multiples of 5 then they will be interpolated.

• Fixes for Predheat, max power is now output power not input, interpolate tables by @springfall2008 in #1737
• Predheat typo for gas mode by @springfall2008 in #1738
