Update EZSP firmware repository for (old) Sonoff Zigbee Bridge to support EZSP v13

[lrswss]

PROBLEM DESCRIPTION

The most recent EZSP firmware 7.4.x for the Sonoff Zigbee Bridge (2020) is missing from tools/fw_SonoffZigbeeBridge_ezsp. The new firmware supporting EZSP v13 is required to keep the old Sonoff Zigbee Bridge working with Zigbee2Mqtt, which has recently introduced the new ember adapter to communicate with Zigbee Dongles. The ember adapter is about to replace the old ezsp adapter.

REQUESTED INFORMATION

• [x] Searched the problem in the docs - only refers to old v6.7.x releases with outdated EZSP v8 support
• [x] Device used: Sonoff Zigbee Bridge (2020) configure as "Sonoff ZHABridge (0)" with Ziggbee2Mqtt 1.3.8
• [x] Tasmota precompiled binary firmware version number used: 13.4.0 with ncp-uart-sw_7.4.3.0_115200.ota firmware

ADDITIONAL CONTEXT

New EZSP firmware releases: https://github.com/xsp1989/zigbeeFirmware/tree/master/firmware/ZigbeeBridge_SM-011-signed

AFAIK, the newest versions are not working with Tasmota Z2T.

Anyway, do not open an "issue", when it is not an issue to be fixed, just a suggestion.

Well, my old Sonoff Zigbee Bridge with Tasmota 13.4.0 running in "ZHA Bridge (0)" mode and most recent EZSP firmware ncp-uart-sw_7.4.3.0_115200.ota is working perfectly for me with current Zigbee2MQTT v1.3.8. I had to upgrade from previous 6.7.x EZP firmware to 7.4.x to get it working again after upgrading from Z2M 1.3.4. Since the ezsp adapter is already marked as deprecated in Z2M other people might run into the same problem using the oudated 6.7.x EZSP firmware with Tasmota.
