Bump brother library, use pysnmp-lextudio with SNMP integration

Breaking change

Proposed change

Currently, SNMP integration and brother library use this pysnmp fork, which is not compatible with python 3.12 and is rarely updated. The author of the original pysnmp library has passed away.
I suggest changing the library for snmp integration and brother library to pysnmp-lexstudio, which is compatible with python 3.12.

I tested HA running under python 3.12 and both brother integration and snmp sensor work fine.

I'll test it shortly.

It seems reasonable to me as otherwise we have no snmp support shortly once we go to py3.12

Test build for wheels https://github.com/home-assistant/core/actions/runs/7187364812

Wheels look ok. Tested on my production where I use snmp but not brother and all is working as expected 👍

Thanks @bieniu

Looks like that brings us down to only 4 integrations that don't support 3.12 and thankfully they almost all have anemic usage except for metoffice
