Lack of aarch64 support

[hiteshbhatia3559]

Environment information

• py-solc-x Version: 1.1.1
• solc Version: 0.6.0
• Python Version: 3.9.5
• OS: linux/aarch64

What was wrong?

As per this PR #66 , aarch64 support was added, and no commits/changes were made to the relevant code. In the current master however these functions simply don't exist, see https://github.com/iamdefinitelyahuman/py-solc-x/blob/master/solcx/install.py

After installing py-solc-x attempting to run install_solcx('0.6.0'), the error
OSError: [Errno 8] Exec format error: '/home/ubuntu/.solcx/solc-v0.6.0' is shown.

How can it be fixed?

I suppose aarch64 support could be added back? I'm not aware of how, however.

Additionally when calling compile_solc('0.6.0'), compilation fails. Following is the log

During handling of the above exception, another exception occurred:

This is likely due to a missing or incorrect version of a build dependency.

It's probably not the cause of this error since this is building 0.6.0 but please note that install_deps.sh has been recently removed from the Solidity repo: ethereum/solidity#9582.
