Add package: mahotas

[IsakTheHacker]

Fixes #373

[mhsmith]

Thanks for the PR. To add a new package, we need a test script to verify that it works. Please do the following:

• Follow the instructions in "Testing a package" in the README.
• Push your test script to this PR.
• Post a comment saying which Python versions and ABIs you have tested.

What's the status of this PR? Are the tests passing now?

I don't know how to proceed further with this information, could you take a look at it?

[mhsmith]

You should probably replace the build requirement with a host requirement for Chaquopy's own version of NumPy. For example, see packages/pandas/meta.yaml.

You'll probably also need a patch similar to the one in the pandas recipe, so it can find the NumPy include directory during the build.

[IsakTheHacker]

I have implemented your suggestions, but I can't currently build the package on my machine due to an issue with my local Python installation (and I don't have time to fix it at the moment). Could you build the wheel and run the tests to see if they are passing now?

[mhsmith]

There's no hurry, just let me know when you've had a chance to test it yourself.

[mhsmith]

Changing to draft until tests are ready.
