feature: add Chromium extensions

[srbrunner]

Feature Request

Specifications:

• App Version: v3.13.0
• OS macOS:

Description:
Is it possible to add Chromium extensions so we can add support for password managers. For example I use 1password and it would be helpful if I could launch the Chromium extension so I could auto populate username, passwords, and 2FA without having to leave singlebox or the webcatalog app.

Additional Context
The Electron project is already working on this and there is a stack overflow discussing implementation possibilities too

Thanks a lot for submitting this. I'll definitely add extension support to Singlebox when Electron extensions API becomes more stable.

Related to #710.
