dependency on deprecated 'future'

[onkelbeh]

Hello,

first, I hope you don't mind I included your component for Home Assistant Gentoo Overlay.

It uses a dependency on 'dev-python/future', and I now have received a deprecation notice.
This library was made for Python 2 compatibility, and is redundant. Many linux distributions work on removal.

It had to be patched to work with Python 3.9+ and is also vulnerable to CVE-2022-40899.

Would it be possible to switch to a different library?
Thanks a lot.

\B.
