[FEATURE] Replace open_filex by open_file

[EArminjon]

Is your feature request related to a problem? Please describe. open_filex is a fork of open_file and both package can't live together if i'm not wrong.

Describe the solution you'd like If possible remove open_filex and use open_file. Open_file receive a lot of fix and maybe the usage of the fork is no longer required.

Describe alternatives you've considered

@EArminjon hmm, not sure. At the moment of writing open_filex looks more up to date than open_file.

@EArminjon @techouse While this is true, the downside of using open_filex is that it has some permissions in it's Android manifest file that Google Play Store complains about. This prevents us from distributing internal test builds with Alice enabled.

The permissions in question:

<uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
<uses-permission android:name="android.permission.READ_MEDIA_VIDEO" />
<uses-permission android:name="android.permission.READ_MEDIA_AUDIO" />

So in conclusion - while both packages are maintained I think that open_file is preferable because it does have a better approach to handling sensitive permissions.
