`numpy.complex` is deprecated

[eigenvivek]

Running the example in kspace.py raises the following error:

AttributeError: module 'numpy' has no attribute 'complex'.
`np.complex` was a deprecated alias for the builtin `complex`. To avoid this error in existing code, use `complex` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.complex128` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

Fix would appear to be replacing every instance of dtype=np.complex with dtype=complex. Happy submit a PR for this!

Running in a clean environment with only pygrappa, phantominator, and jupyter installed:

Thanks for submitting @eigenvivek, I'll try to reproduce locally -- I agree that a fix should be pretty simple, but I'd like to take a look at this repo again and see if anything else needs updating, it's been a minute :)

[eigenvivek]

Sounds good -- thanks for the package, it's been very useful for prototyping!

[mckib2]

Just released version 0.7.0 on PyPI which should resolve this issue. Let me know if you run into anything else!
