Improves the current implementation of the parse() method to scan the entire sentence and count the fields before attempting to read the fields. This prevents accidental invalid pointer accesses when parsing invalid sentences with valid checksums. The new parse implementation also has a smaller compiled size. Includes a sketch in the "extras" directory (ignored by the Arduino IDE according to the library spec) that was used for testing the parsing of all sentences known to the parser.
Implementation of isEmpty() was incorrect since it performed a null check after dereferencing the pointer

This pull request fixes issues #128 #153 and #154
It has been thoroughly tested and creates a smaller footprint than the original parser, so it should
not cause issues with the Arduino Uno.
