Draft: feat(widgets/console): BECConsole based on termqt added

Description

Demo widget base on termqt. ATM there is no qt6 support so if someone wants to test this widget, then you have to git clone my fork and install locally. Once my pull request will be merged, I can put termqt as a dependence to bec_widgets.

Type of Change

• new BECConsole

Potential side effects

Will not work on master until termqt is dependency.
