Adding register for Hot water start to NIBE S1156 / S1256 / S1155 / S1255

[KptnHaddock]

Hi,
Thank you for initiating and mainting this integration. I have now used it for some months and it works great with HA and my newly installed Nibe s1256.
Have been trying to understand why one particual register listed in the Nibe Modbus technical desciption does not show up in the integration, the Hot water start (BT5). My understanding is the s1256 integration is based on extension file nibe/data/s1155_s1255.json, where this particual register seems to be missing. Whould it be possible to somehow get it in?

Here is how Hot water start is defined in the .csv file, exported from the heatpump.

Title	Register type	Register	Division factor	Unit	Size of variable	Min value	Max value	Default value
Hot water start (BT5)	MODBUS_INPUT_REGISTER	2014	10	°C	2	0	0	0

I would be happy to contribute but need some guidance on what to edit where as my gihub experience is very limited.
