Add aarch64 wheel build support

[odidev]

Add aarch64 wheel build support.
Related to #23 @SteveDiamond Could you please review this PR?

[odidev]

The build for arm64-graviton is passing in Travis-ci.com. Travis-ci.org will be shutting down soon, so it would be great if you migrate the repo to Travis-ci.com.

[SteveDiamond]

@odidev I can't migrate this repo to travis.com. It's not giving me the option. I think the embotech organization would need to. I can approve this change regardless though.

[odidev]

@adomahidi, what are your thoughts on migrating ecos-python to travisci.com, as travisci.org will be shutting down soon.

[adomahidi]

Fine for me!

[odidev]

@adomahidi, could you please do the needful? Thanks in advance.

[adomahidi]

Done, but there's an error for aarch64. Logfile:
I don't have time to debug this, please advise

I have run the build on travis-ci.com and the arm64 build is passing successfully.

Travis-ci Logs - https://travis-ci.com/github/odidev/ecos-python/builds/223701473

Could you please re-trigger the build and if it still fails, I will look into it.

[adomahidi]

yeap looking good - so all set here, right?

[odidev]

Yes, I think retriggering the build will solve the problem.
