reddit: Support PRAW 7

[RhinosF1]

The problem

I can't update praw to version 7
$ pip3 check sopel 7.0.4 has requirement praw<6.0.0,>=4.0.0, but you have praw 7.1.0. praw 7.1.0 has requirement prawcore<2.0,>=1.3.0, but you have prawcore 0.14.0. The command "pip3 check" exited with 1.

The solution

Support the latest version of praw

But why does it matter?

Haven't checked the API changes for newer PRAW versions, but if you have something else installed that needs more recent PRAW that's kind of what venvs are for.

We just like to ensure things are kept up to date. It's 100% low priority and a nice to be.

Looks like the current praw version range was selected to match Sopel's Python release compatibility as closely as possible without needing to use environment specifiers. Slotting this for 8.0, since we'll be dropping old Pythons then.

(We'll probably also split the reddit plugin out into its own package, but this issue can just be moved to the new repo if that happens first.)

I'd also want to thoroughly verify that everything in reddit.py still functions 100% without stripping functionality.

@deathbybandaid That's (theoretically) why we have tests. Missing examples should be added for code paths that aren't covered.
