serial poll() is always reading only 1 byte per call

[ku3i]

Arduino_MKRGPS/src/GPS.cpp

Line 195 in c736985

if (_stream->available()) {

The current version is "taking forever" to read a GPS location, if the user has a significant delay (e.g. 500ms) in the loop() method, since on each GPS.available() call only 1 byte is read.

proposed fix: replace the "if" with a "while" in line 195 (GPS.cpp)

Another tip: make the GPS_DEBUG flag available in the begin() method (2nd argument or so), to better track issues like this easily and without modifying the library.

Yes i have modified the library this way and work perfectly with a delay of 300ms on the loop which read GPS data.
