[REQUEST] EmberZNet 6.8.0 NCP application firmware for EFR32

[Hedda]

@mtx512 OK to request or suggest that release precompiled EmberZNet 6.8 NCP application firmware as optional downloads?

Silicon Labs EmberZNet SDK version 6.8.0 (6.8.0.2) was released this summer so it is new but not quite cutting-edge any more.

Mostly interesting in testing this on the Sonoff ZBBridge (Sonoff Zigbee Bridge) by ITead with Tasmota zbbridge as it is versatile.

Preferably also as a Sonoff key signed firmware in an OTA image format as well that can be flashed with Tasmota itself:

Sonoff ZBBridge when flashed with Tasmota zbbridge and custom EmberZNet firmware firmware can be used in two ways:

Sonoff ZBBridge as a remote pass-through WiFi bridge adapter to be used by other software like Home Assistant ZHA:

Zigbee2Tasmota (Z2T) is Tasmota's own native Zigbee to MQTT solution which is lightweight but not very user-friendly:

Notes

Please note that release notes say that EmberZNet PRO stack version 6.8.x requires latest Simplicity Studio 5 (SSv5) which is new.

Might be nice for developers and users to have the option to upgrade to the latest and greatest firmware available from SiLabs ;)

Major new Zigbee feature in EmberZNet 6.8 and later is support for concurrent multiple PANs (multi-PAN) on one coordinator:

There is also support for "Dynamic Multiprotocol Development with Bluetooth and Zigbee" which might not be as interesting.
