Add linux aarch64 wheel build support

Added linux aarch64 wheel build support.
Related to #65. @polm Could you please review this PR?

Thanks, this would be a great feature to have! I'm kind of busy this week but I'll take a look at this soon.

Sorry it took me a while to get to this. I have a Raspi I thought I could test this on but turns out it's a bit too old to be aarch64.

Your changes look fine, so what I'll do is merge them and do a test release.

Thanks again for the PR!

In an incredible stroke of bad luck it seems Github Actions is having issues tonight, I'll check out the results later.

An alpha release is up and running and can be installed with this command:

pip install mecab-python3==1.0.4a2

Can you confirm that works for you?

For the record, one change I had to make was disabling building wheels with Python 3.5, which doesn't seem to be supported any more.

@polm, Thanks. I installed the aarch64 using pip install mecab-python3==1.0.4a2 and it is working as expected. Below are the installation logs:

Thanks, I had another user install it successfully on arm64 Linux so I guess this works. Thanks again for the PR!
