Updated to new Arduino library structure

Updating repo to fit [Arduino library specifications](https://github.com/arduino/Arduino/wiki/Arduino-IDE-1.5:-Library-specification):

- update ".../examples" path
- update ".../src path" for .cpp and .h files
- remove "FPS_GT511C3" path
- add "libraries.properties"
update "keywords.txt" path
-Adding "library.json file" for PlatformIO
