Fstrs everywhere

[antazoey]

Migrating code to be more py3-y by using f-strs everywhere where it makes sense. Note, it does not always make sense, such as in the following conditions:

• You are interpolating an expression involving slashes /
• You are building a dict of values to pass into format
• You are using a str-template pattern

F-str makes sense in most cases however.

@unparalleled-js I think you could get this to be something that tox style would do for you automatically if we modified .pre-commit-config.yaml to pass different args to pyupgrade, namely:

 args: ["--py36-plus"]
