Drop Python 3.6, enable Apple Silicon wheels for Python 3.8, 3.9 and 3.10, upgrade to manylinux2014

[MonkeyBreaker]

This PR provide wheels for the new Apple Silicon for Python 3.8, 3.9 and 3.10.
Unfortunately, for the moment the wheels can be generated but cannot be tested because Github Action runner do not have a native ARM runner for MacOS.

I did not find if a public statement will provide in a near future support for native ARM runners. But on the meantime we can already generate the wheels and anybody that has a Mac with the new Silicon can perform the test on his/her machine and let us if it works. And only then, we will upload the new wheels on Pypi.

Unfortunately I do not have this kind of machine available.

Of course another option would be to emulate the hardware, but, for the moment I do not have the time to deploy this kind of feature.

The wheels are available here If anybody with latest Apple Silicon can download them and test them locally I will be more than glad :)

I can do this!

@MonkeyBreaker I guess the wheels need to be re-generated since #56 was merged. I'm ready to test them once you've done so.

@ulupo here just out of the oven :)

I cannot even use the universal2 wheels on my machine. Opening the interpreter in the environment in which I have installed the wheels, I get:

>>> import gph

[ulupo]

Perhaps this should be x86_64 arm64 universal2 to solve my issues?

[ulupo]

I added this, re-generated the wheels, but still get the same error as before!

Could this be related? Unidata/netcdf4-python#1148 (comment)

[ulupo]

I'm happy to help complete work on this PR. As we discussed, Python 3.6 should be removed and we should adopt manylinux2014 for all python versions (now we only use it for Python 3.10). Perhaps Python 3.7 can now be covered too with macOS ARM wheels? I will then test the wheels on my M1 machine.

[MonkeyBreaker]

Support to Python 3.6 dropped

[ulupo]

Formally approved, but waiting for @MonkeyBreaker's last look!
