EM101 false positive

Summary

import typing

raise typing.cast("Exception", None)

The fix for EM101 is applied.

which becomes:

import typing

msg = "Exception"
raise typing.cast(msg, None)

then the fix for TC006 is applied.

which becomes:

import typing

msg = "Exception"
raise typing.cast("msg", None)

and it becomes a loop, since that introduces EM101 again.

Thanks. I think it makes sense to exclude typing.cast from EM101 (I'm a bit surprised that we flag any function call and not just calls to classes (variables starting with an uppercase character)
