feat: add replicate.use()

[dgellow]

Part of #32

This pull requests adds the helper method replicate.use(), as defined here.

See the script examples/use_demo.py.

Some things that are still a work in progress:

• type checking is currently broken in a lots of places. The stainless sdk targets python 3.8, while the current replicate sdk targets 3.12 (and uses a good number of 3.12 typing features). That makes porting the code a bit more complicated, but it's not a blocker
• tests haven't been ported yet
• the original code had the following:

# TODO
# - [ ] Support text streaming
# - [ ] Support file streaming

I kept it as-is, though I'm a little bit confusing, because text streaming is working?

• need more QA, testing I'm sure some things are broken :)
• I didn't look at adding docs

@zeke Do you prefer:

1. already merge that PR as-is, then continue with more focused PRs. That means linter checks will fail for the time being
2. keep that PR open until everything is fixed

It's up to you, if you already want to try out replicate.use(), merging will make that easier.

Nice work, @dgellow. How about this:

1. Turn CI green by fixing linter stuff
2. Merge this and cut a prerelease so we can play around with it
3. Follow up in other PRs for type checking, tests, and docs

I've updated the body of issue #32 with a task list to this effect, and updated your Fixes #32 comment above to Part of #32 so it won't automatically close the issue when we merge this.

Sound good?

Sounds good, though I will have to take a few shortcuts to make CI green (the vast majority of linter complains are around type checking issues)
