* feat: add 'CompactPopupWidget' container widget
Makes it easy to write widgets which can have a compact
representation with LED-like global state indicator,
with the possibility to display a popup dialog with more
complete UI ([`49268e3`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/49268e3829406d70b09e4d88989812f5578e46f4))

is emitted multiple times. ([`f084e25`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/f084e2514bc9459cccaa951b79044bc25884e738))

Launcher for BEC GUI Applications
Application must be located in bec_widgets/applications ;
in order for the launcher to find the application, it has to be put in
a subdirectory with the same name as the main Python module:
/bec_widgets/applications
├── alignment
│ └── alignment_1d
│ └── alignment_1d.py
├── other_app
└── other_app.py
The tree above would contain 2 applications, alignment_1d and other_app.
The Python module for the application must have `if __name__ == "__main__":`
