Add linting for exception chaining with raise-from

[pseudo-rnd-thoughts]

describe the request

It would be interesting to add a linting check for exception chaining, i.e., raising new exception with catch case using the raise from style

try:
   * code causes an exception * 
except Exception as e:
    raise TypeError("...") from e

Based on this blog post - https://blog.ram.rachum.com/post/621791438475296768/improving-python-exception-chaining-with

This rule has already been added to pylint, pylint-dev/pylint#3695
But the rule seems to be relevant to flake8 as well

I have looked through the issues and couldn't find a similar request, apologies if already requested.

From the issue template: NOTE: flake8 is a linting framework and does not implement any checks

@sigmavirus24 The sentence "flake8 is a linting framework and does not implement any checks" makes perfect sense, assuming you also know the author's definitions for "linting" and "checks". Are these definitions available?

[sigmavirus24]

They're in flake8 documentation. Regardless. The original post asks for a pint which is the same language used in the template
