missing charset_normalizer dependency

[KellyP5]

Prerequisites

• I am using the latest version of Locust
• I am reporting a bug, not asking a question

Description

It appears that d4d92dc introduced charset_normalizer as a dependency without explciitely including it in https://github.com/locustio/locust/blob/master/pyproject.toml

This means on import if you are using locust library but don't have charset_normalizer installed you will end up with:

[2023-12-06T16:04:04.623Z] ImportError while loading conftest '/workarea/locust_tests/conftest.py'.

charset-normalizer is a dependency of requests, so this shouldnt be necessary. Are you sure you didnt just have a broken install somehow?

Hi, I've just got the same issue here. I was updating from an older version.

There is a dependency called 'charset-normalizer' which is missing. Perhaps on new installation, this does not happen, but I would add it in the requirements.txt just in case.

Perhaps it is an issue with older versions of requests. Since multiple people seem to have the issue I have merged the PR.
