Pydash

-------------------

- Add ``pipe`` and ``pipe_right`` as aliases of ``flow`` and ``flow_right``.
- Fix ``merge`` so that trailing ``{}`` or ``[]`` don't overwrite previous source values.
- Make ``py_`` an alias for ``_``.

-------------------

- Support ``type`` callbacks (e.g. ``int``, ``float``, ``str``, etc.) by only passing a single callback argument when invoking the callback.
- Drop official support for Python 3.2. Too many testing dependencies no longer work on it.

-------------------

- Add ``append``.
- Add ``deep_get``.
- Add ``deep_has``.
- Add ``deep_map_values``.
- Add ``deep_set``.
- Add ``deep_pluck``.

- Add ``join``.
- Add ``pop``.
- Add ``push``.
- Add ``reverse``.
- Add ``shift``.
- Add ``sort``.
- Add ``splice``.
- Add ``unshift``.
- Add ``url``.
- Fix bug in ``snake_case`` that resulted in returned string not being converted to lower case.
- Fix bug in chaining method access test which skipped the actual test.
- Make ``_`` instance alias method access to methods with a trailing underscore in their name. For example, ``_.map()`` becomes an alias for ``map_()``.
- Make ``deep_prop`` an alias of ``deep_property``.
- Make ``has`` work with deep paths.
- Make ``has_path`` an alias of ``deep_has``.
- Make ``get_path`` handle escaping the ``.`` delimiter for string keys.
- Make ``get_path`` handle list indexing using strings such as ``'0.1.2'`` to access ``'value'`` in ``[[0, [0, 0, 'value']]]``.
- Make ``concat`` an alias of ``cat``.

-------------------

- Add ``add``, ``sum_``.
- Add ``average``, ``avg``, ``mean``.
- Add ``mapiter``.
- Add ``median``.
- Add ``moving_average``, ``moving_avg``.
- Add ``power``, ``pow_``.
- Add ``round_``, ``curve``.
- Add ``scale``.
- Add ``slope``.
- Add ``std_deviation``, ``sigma``.
- Add ``transpose``.
- Add ``variance``.
- Add ``zscore``.
