LICENSE installed in toplevel

[APN-Pucky]

Gentoo#s build system complains. I think the include = [LICENSE] in pyproject.toml can be removed.

* The following unexpected files/directories were found top-level
* in the site-packages directory:
* 
*   /usr/lib/python3.11/site-packages/LICENSE
* 
* This is most likely a bug in the build system.  More information
* can be found in the Python Guide:
