Allenw/interp scalars

[allen-adastra]

Add support for scalar query points.

This isn't the most elegant way of going about it, would welcome other ideas.

I will note that currently on main, if I input a scalar as a 1d array, we fail the jax.grad test it seems.

Also increase jax version range up to 0.4.20.

Thanks for the PR! My bad for not checking for scalar inputs 😴

Looks like the tests are failing due to some deprecation warnings in newer versions of JAX, can you take a look? Also looks like some formatting/linting issues, pre-commit (yml file https://github.com/f0uriest/interpax/blob/main/.pre-commit-config.yaml) should take care of it.

Thanks for making this package! Def something that is sorely needed.

Sorted out the deprecation matter and ran the pre-commit (whoops, didn't install).

I also recently tried this new linter/formatter that has been exploding in popularity. Will say it's been a good move for me:
