New Tuya firmware from last month (SmartLife, firmware 1.6.1 on Teckin 13w bulbs)

Hello, newbie here.

I successfully used tuya-convert for all of my Tuya devices at home, although I had 4 out of 5 of some nice 13W bulbs ( https://www.amazon.com/TECKIN-Changing-Equivalent-Compatible-2900K-6000K/dp/B07RZKV7FQ/ ) were recently updated to SmartLife (tuya)'s new firmware last month version 1.6.1, so for those I had to access the PIN inside the lights in order to flash the firmware since they refused to go further than "resending packets" in the OTA process.

I am on Mac, I used the Tazmotizer app, and I did a backup of that new firmware thinking that it might help the owner of this repo to find a way to update the OTA tool in response to this new tuya patched firmware… 

If this can be of any help, just let me know where Tazmotizer stores its back-ups (I can't find this information on Google lol) and I'll send it to you!

Thanks for your amazing work!

Start by reproducing the OTA failure on the Teckin 13W bulbs with SmartLife firmware 1.6.1 and review the backed-up firmware from Tazmotizer. Determine whether the backup contains enough information to investigate compatibility with tuya-convert; done would mean a confirmed path for updating the OTA process or a documented reason it cannot support this firmware.
