feat(adapter): add optional STAT_STATUS processing to generate Mac datapoint

[baetzst]

🆕 Processing of stat/STATUS* to generate the MAC datapoint

Description

This pull request extends the Sonoff adapter with optional processing of stat/STATUS* MQTT topics. The primary purpose of this change is the generation of the MAC address datapoint, as all Tasmota devices publish the MAC address exclusively via stat/<topic>/STATUS5.

Changes in detail

• New configuration option

  • Added STAT_STATUS checkbox to the admin UI
  • Enables processing of stat/<topic>/STATUS*

• MQTT processing

  • Extended topic detection to support stat/STATUS\d*
  • Parsing of STATUS payloads (StatusNET)

• Datapoints

  • Added new Mac datapoint
  • Automatically created when StatusNET.Mac is received

• Tests

  • Added integration test for stat/.../STATUS5
  • Extended test configuration with STAT_STATUS

Motivation

The MAC address is a key identifier for Tasmota devices. Since it is not published via tele or stat/RESULT topics, but exclusively via stat/STATUS5, additional STATUS processing is required.
