Add setting to override detected country for Tor bridge configuration
I am using briar 1.2.4 and I noticed in the options that Briar incorrectly selects 'connect via internet (tor automatic based on location'.
I was on holiday on country X and I did not installed Briar there, however when I went home (country Y) and installed Briar, the option connect via internet (tor) automatic based on location' was wrong as it referred to country X not my current location.
I don't know whether briar got the info from f-droid since I opened it when I was in country X, however I think this can be dangerous as different countries have different degrees of repression, and tor should be set accordingly, therefore I suggest that whenever the app is opened to check if there was a change of location or maybe even let the user mention which country and automatically set the best connection accordingly.
