Improved Sending Data

Changes:

• The send_data method can now send metadata associated with the data point. You can also now set the amount of precision associated with floating point values. #92

• This change will break code using the send_location_data() method. Code using this method will need to be changed to use the updated send_data method.

  • The Adafruit IO Python Location example has been updated to reflect usage of the new send_data method

To use in CPython, pip3 install adafruit-io.
