[NOT READY] Selective permissions

[chrusart]

Now you can create RNPPermissions.xcconfig file in ios/ folder and provide preprocessor variables e.g.:

RNP_SELECTIVE = RNP_PERMISSIONS_SELECTIVE
RNP_PERMISSION_TYPES = RNP_TYPE_LOCATION RNP_TYPE_NOTIFICATION

Only code responsible for particular permission will be compiled in and no need to include all usage descriptions in Info.plist.

By default it includes all if RNP_PERMISSIONS_SELECTIVE not given, but I think in future it should be always a list of needed permission types.

Some refactoring done as well, docs will be added if will be some response from maintainer as this repo wasn't updated for some time.

To use this implementation:

"react-native-permissions": "github:flatfox-ag/react-native-permissions#7683bceac6f152d74e98574eb90916bad3b2363b",

Any feedback welcome.

Well, it still deosn't work, something still to be done. Working on it. Or it's other library.

I have to abandon this pr, can't get it to work.

[chrusart]

I just couldn't get preprocessor macros to work, for example:

with simple RNP_PERMISSION_TYPES = RNP_TYPE_LOCATION in RNPPermissions.xcconfig,
it is in Release/Debug preprocessor macros in ReactNativePermissions xcode project,

#ifdef RNP_TYPE_LOCATION
             @(RNPTypeLocation) : @"RNPLocation",
#endif

is normally highlighted in XCode as it should be compiled,
but actually is not, when dubugging, NSDictionary is empty, i'm not sure what I'm missing here, i tried few approaches.

If somebody will point error I will for sure finish this pr and resubmit.
