feat: load dashboard data of source1 (gas boiler) and fireplace

[jkremlacek]

Adds 3 new entries from dashboard that are optional and depending on specific home installation:

• fireplace
  • pump running
  • actual temperature
• source 1 heating demand

Note 1: Source 1 is Regulus UI naming (detail page under /EN/ZD_S.XML), however visual (and in reality) is that it represents gas boiler:

Note 2: Registry mapper contains additional necessary changes to correctly map values in my installation, questionable if original values work for someone else, then which version should be used by the integration

---

Examples of working changes:
Regulus UI:

looks good.
Also I have a doubt how the same version may have different mappings. The original mapper v 1.0.11.16 has been provided by @grecoit. Maybe you can compare your xmls and negotiate the differences.
Will merge it and make next release in a few days.
thanks

Regarding XMLs, here are mine input values (omitting page and access elements as they might contain some private info)
regulus_dashboard.xml

If @grecoit posts their, we can compare it and see what can be done - maybe two mapping variants for same firmware version (_a, _b) would have to be made.
