Broken with Autmatic1111 v1.6.0

Here is the error from console which breaks this extension from working, when used with latest version of Automatic1111.

*** Error executing callback ui_tabs_callback for C:\Softwares\Graphics\stable-diffusion\stable-diffusion-webui\extensions\SD-Prompt-Enhancer\scripts\sd_prompt_enhancer.py

Start in scripts/sd_prompt_enhancer.py at line 194 and compare its call into modules/ui_extra_networks.py, where line 384 raises the reported TypeError under Automatic1111 v1.6.0. Reproduce the extension startup with that version and inspect the create_ui arguments; done means the extension loads without the ui_tabs_callback error.
