Changes:
- Added support to escape 2-dimensional np.ndarray.
- Added support to decode BIT column.
- The argument 'many' for 'cur.execute()' and the 'cur.executemany()' method now affects all sequence/mapping types (previously list & tuple only).
- Optimized pool connection reset (consistency). Now support change 'autocommit' mode, 'use_decimal', 'decode_bit', and 'decode_json' at pool level, which affects all pool connections at 'acquire()'.
- Added custom types: <'BIT'>, <'JSON'>. Act as a wrapper so the 'escape()' function can identify and escape the value to the desired literal format.
- Improved class & method documentation.
- Bugfixs and optimizations.
