spot pointless f-strings?

[peterjc]

See flake8-pie's PIE782 code, since disabled due to false positives:

sbdchd/flake8-pie#24

The idea is to treat things like the following as a special case:

print(f"Hello world!")

In that example the f-prefix can be omitted, a plain string literal is enough:

print("Hello world!")

This is covered by flake8 F541 since pyflakes 2.2.0 (released 2020-04-08).
