Vl53 long range (#1055)

* Update vl53l0x_sensor.cpp

Changed values for long range support

* added true / false option for long range detection

* debug missing ,

* further debug option long_range

* Travis updates

* added travis tests

* Travis removed space should be good now

* update to trigger travis again

* added old test files for PR

* added vl5310x sensor for compile testing

* fix variable names
