pkg_resources is no longer accessible by default in Python 3.12, which means this library is incompatible with Python 3.12. This PR moves from using pkg_resources to importlib.metadata which is the intended way of replacing the metadata API of pgk_resources. See here.

Since pkg_resources is only included in Python 3.8+, this PR also drops support for early versions of Python. If support for these older versions is something that we want to keep, I'm happy to go and add in conditional logic to use a backport for older versions to maintain compatibility, but as 3.7 is now in end-of-life I assumed we might want to drop support now.

Fixes #874.

* Add sample code to handle Base64 fields in drf-extra-fields project

* Fix format for .rst

* Update answer to the easier version as suggested in Hipo/drf-extra-fields#66 (comment)

* update readme.rst

`permission_classes` expects tuple but list was provided

* Check for allow_null attribute

* Add utf-8 support for generated formats

* Added `many` support to example code.

* serialize pytz object as a string

* simplify if condition

* handle errors rendering with TemplateHTMLRenderer

This change fixes an `OPTIONS` request to the API page which will return
a successful response, but the `TemplateHTMLRender` will not be prepared
to render it since there is no template name provided in either the view
or response [1].

* Declare Django 3.2 support in README, classifiers

This commit will make sure that `Django :: 3.2` will show up in the
classifiers list on PyPI: https://pypi.org/project/drf-yasg/

(The magic happens because we parse the README to get supported Django):
https://github.com/DavidCain/drf-yasg/blob/ee29412d3cdb311/setup.py#L36

3.2 support should already exist
================================
A closed pull request, axnsan12#735,
noted support for Django 3.2 in both `tox.ini`, and the README.

That PR was closed in favor of
axnsan12#741, which edited `tox.ini`
and switched to GitHub Actions.

axnsan12#735 (comment)

This project has been testing on Django 3.2 for a long time (about a
year). I think we can declare it supported it the README!

* Fix `pip install` command for contributors on zsh

On `zsh` (a popular shell, and the default for macOS), install fails:

    $ pip install -U -e .[validation]
    zsh: no matches found: .[validation]

Quote the arguments so that `bash` or `zsh` will succeed.

@max-muoto Id like to keep the support for python 3.6 and 3.7 since a lot of our users are tied to those versions and compatibility is a priority. Could you add them back? Looks like the tox command is failing for python 3.12, could you try running it locally and see why? Thank you!

Sounds good, I'll make sure we keep support there. Let me give it a try locally!

@JoelLefkowitz 3.12 failures seem to be coming from usage of https://github.com/Yelp/swagger_spec_validator which appears to be unmaintained. Any ideas on potential workarounds here? Not sure how deep drf-yasg relies on this library.

They have the same issue around pgk_resources usage.

@max-muoto It says here setuptools isn't available by default anymore python/cpython#95299. I've added it to the dependencies list and the python3.12 tests are now passing. I'm going to update the PR target to the release branch. Looks like flake8 is failing in the python 3.8 runs, could you take a look please?
Thank you
