Final 2.5.0 release (PyPi published) - Converters, construct_dict, get_function_params and more!

2.5.0 - Converters, construct_dict, get_function_params

• Includes commit 12da829 which enables 2.5.0 to function fully on Python 3.6 and 3.7 (prior to this commit
  some tests only worked on 3.8+)

commit 12da829
Date:   Thu Dec 5 02:39:32 2019 +0000
Add local_tests.sh, fix get_function_params on older python

     - Added `local_tests.sh` for running the unit tests on multiple python versions locally
     - Added `OrderedDictObject` to collections module, since python versions before 3.8 cannot reverse a normal dict.
     - Add unit tests for ordered dict object
     - Adjusted `get_function_params` to use the new OrderedDictObject (fixes failing tests on older python versions)

New Features / Additions

• privex.helpers.common
  • Added get_function_params - which extracts and filters a function/method or class constructor's parameters, and
    outputs them in a dictionary
  • Added construct_dict, which allows you to either construct a class, or call a function using a dictionary of keyword arguments,
    using get_function_params to detect what arguments the class/function/method can take, including any parent classes, then
    filtering out any keyword arguments which would otherwise be rejected and cause a TypeError.
  • Added _filter_params, a private function used by the aforementioned functions to filter a dictionary or iterable of Parameter objects.
• New module converters, containing functions/classes designed to convert/parse one type into another
  • convert_datetime converts both string date/time's as well as unix timestamps into datetime.datetime objects using dateutil.parser
  • convert_unixtime_datetime converts specifically UNIX epoch timestamps (can be string, int, float, Decimal etc.) into datetime.datetime objects,
    and is used by convert_datetime to handle unix timestamps.
  • convert_bool_int converts booleans True / False as well as string / int versions into integers 1 (true) and 0 (false)
  • convert_int_bool is mostly an alias to is_true, but exists for convenience and semantics (if there's a convert_bool_int, why not a convert_int_bool?)

Changes / Updates

• Shrank the rather large copyright notice in most modules down to the small copyright block, and instead of dumping the whole X11 / MIT License text in there,
  the licence block simply states License: X11 / MIT. This should make the docs a bit more readable.

• Added python-dateutil to the Pipfile

• For sanity reasons, python-dateutil has been added to the install_requires (meaning it's auto-installed when you install privex-helpers). The package is relatively
  small and depends on just six, weighing in around 500kb (python-dateutil = 468kb, six = 36kb).

  It may be removed and refactored into a setup.py extra at a later point, but for now it's small and commonly required enough that it can be a dependency.

• Added dateutil to the sphinx intersphinx mapping

• Possibly other small changes I forgot to include

Testing

• Added new test case TestInspectFunctions to test_general, which tests the new get_function_params and construct_dict functions.
• Added new test module test_converters.py which contains test cases for the new converters module
  • TestConvertDate covers date/time related converters such as convert_datetime and convert_unixtime_datetime
  • TestConvertGeneral covers other converters that don't fit into a specific category (or would otherwise be pointless to categorize)
