Version 1.3.0 wheel package is missing `py.typed` file about djangorestframework-dataclasses

[intgr]

I think what may have happened is that the build configuration for py.typed was already lost between versions v1.1.1...v1.2.0 in commit 9be33a9

But the build directory from 1.1.1 was re-used for 1.2.0 package, and the stray py.typed file remained from a previous build. I've had similar issues in the past with unclean build directories.

Hmm, that's strange, I remember checking this when I worked on 9be33a9, but I must've missed something.

But the build directory from 1.1.1 was re-used for 1.2.0 package, and the stray py.typed file remained from a previous build.

AFAIK python -m build (which I use) runs every build in a clean environment, so this shouldn't happen.

In any case, your PR looks good, I've merged it; thanks!
