Consider creating a bridge + MEW bundle for offline use

[x1ddos]

This came up while discussing https://github.com/digitalbitbox/bitbox-bridge/issues/7.

Currently, users need to run a separate static file server like python3 -m http.server --bind 127.0.0.1 and open http://localhost:port to access MEW offline. Opening an HTML file directly with a browser is suboptimal. For example, see security considerations and corner cases.

It feels like a bundle of MEW + the bridge including a built-in static file server would be very helpful for those who want to use BitBox02 with MEW offline.

Such a bundle would nicely package everything together: the bridge, MEW release and a static server. It would be an alternative package, released alongside the regular bridge.
