Use locales crash the app on start in release

Am having issues to configure the lib with 3 languages: `en`, `fr` and `de`.

I have found some issues related to the problem, but none worked for me. Some related issues include #89 #110 & #141.

For me the following elements need clarification:

- The `locale.name` uses `fr` or `en`. Should'nt we use a full language and region code like `fr-ch` or `en-uk`? This seems to have been discussed on moment.

- The `locale.name` seems to sometimes require just a language, but sometimes a region too. Depending on moment.js implementation. See `node_modules/moment/locale/*.js` for a list.

- The `locale.config` object : why do we need to pass this as we still import the locale file? Why, if I specify the whole `locale.config` file as a copy of the `moment` lib, I still require `moment` to be imported?

While digging for solutions, I have found none that worked. Seeing the amount of issues are related to localization, there seems to be a lack of documentation and maybe some refactoring is required.

# My current issue

Am just trying to set that up properly for the 3 languages stated above. I have tried many variants, but based on what I have read in the readme and in the related issues, I should do the following:

1. import the moment libs
```
import 'moment'
# required ? import 'moment/min/locales'
import 'moment/locale/en'
import 'moment/locale/de'
import 'moment/locale/fr'
```

Use component as follow:

```
1. Move this case inside
// block for masculine words below.
// See https://github.com/moment/moment/issues/3375
case 'D':
return number + (number === 1 ? 'er' : '');

// Words with masculine grammatical gender: mois, trimestre, jour
default:
case 'M':
case 'Q':
case 'DDD':
case 'd':
return number + (number === 1 ? 'er' : 'e');

// Words with feminine grammatical gender: semaine
case 'w':
case 'W':
return number + (number === 1 ? 're' : 'e');
}
},
week: {
dow: 1, // Monday is the first day of the week.
doy: 4, // The week that contains Jan 4th is the first week of the year.
}, }}
...
```
That does not work and crash on app start on release.

# Hypothese

Couldn't be the import something like:

```
import 'moment'
import 'moment/min/locales'
import localeEnGb from 'moment/locale/en-gb'
import localeDeCh from 'moment/locale/de-ch'
import localeFrCh from 'moment/locale/fr-ch'
```
Then the setup of the component like:

```

Start with the README's locale configuration guidance and the CalendarStrip usage shown in the issue, then compare the mentioned moment/locale imports with the release-start crash. Review related issues #89, #110, and #141; done means the supported setup for en, fr, and de is documented and the release app no longer crashes.
