bug/unstructured[pdf] install bug with uv

[thekaasking]

Describe the bug
Installing the unstructured[pdf] optional module, in a clean virtual environment with uv, does not work out of the box.
Uv is a new tool by Astral (creators of Ruff), for Python venv, package and project management. It is a great tool, but somehow does not work with installing the unstructured[pdf] module. It raises a common pycrypto dependency issue. Manually installing pycryptodome fixes the problem, but with package resolving it can still raise issues.

**To Reproduce **
On PS:

uv venv
.venv\scripts\activate
uv pip install unstructured[pdf]

Expected behavior
You expect the optional module of [pdf] to install correctly, out-of-the-box, with uv.

Environment Info
uv venv, Python 3.11, Windows 10 Enterprise 19045, Intel I7 9700K

use pycryptodomex or something instead of this old jank
