[1.0.dev1] Reinstate httpx.__version__?

[jtpio]

Hey thanks for releasing a 1.0 pre-release.

Trying the pre-release locally in a new environment, it doesn't seem possible to get the version programmatically with httpx.__version__, like it's the case with 0.28.1:

1.0.dev1

0.28.1

Maybe it could be useful to keep httpx.__version__ around for 1.0?

Thanks so much for taking a look!

Yep, useful prompt thanks...

>>> import httpx
>>> httpx.__version__
'1.0.dev2'

In general, it's probably best practice to use importlib.metadata to get the version of packages?

Ooohhh... TIL. Thanks @zanieb.
