Updated Input Parsing

[nmuldavin]

Hi,

I recently implemented magellan to parse user lat-long inputs for a marine-mammal citizen science platform I am working on. Our director (a whale guy) was not happy with the input parsing in certain edge cases so I added a few lines to address those cases. The cases in particular were:

• Space or symbol separated DMD inputs without a decimal such as magellan('12 3'), magellan('12 30'), or magellan('12°3') were parsing as decimal degrees to incorrect values. To address this I added an extra regex looking for symbol patterns indicating that parsing should skip over the DD phase to the DMS/DMD phase.
• The .toDD() method was ignoring direction if the decimal evaluated to zero such that magellan('-12').latitude().toDD() and magellan('12S').toDD() both evaluated to 12.0000. This I addressed just by changing the condition for adding a negative sign.

I hope you find these changes helpful. Thanks for the awesome work! We were looking for a way to automatically allow different lat/long formats your package has been a great solution.

These changes won't parse pure decimal degrees with a direction, e.g. "45.342 N"
