* Refactored ``ts_json:ext_data_to_ejson{1,2}`` from a function that iterates
over a list of extended data properties and returns a transformed list to
``ts_json:ext_data_to_ejson/1``, a function that transforms one extended data
property. The iteration behavior is acheived using ``lists:map/2``.
* Refactored ``ts_json:ejson_to_ext_data{1,2}`` in a similar fashion to
``ts_json:ext_data_to_ejson{1,2}``.
* Fixed ``ts_json:construct_record/3`` to use ``ts_json:ejson_to_ext_data/1``.
