WIP: Adopt the array api

[mwcraig]

This PR makes the necessary changes to adopt the array API. There are still some things to sort out:

• Run tests mostly against numpy, but do one run against jax (or some other non-numpy array library)
• Check for remaining invocations of numpy in the code.
• Check whether changing .data_arr.mask to .data_arr_mask constitutes an API change. If it does (and I think it does) then patch things up so that .data_arr.mask points to .data_arr_mask

Once those are done the next step will be to find an outside reviewer for this...
