Publish pre-built wheels

[csukuangfj]

This PR publishes pre-built wheels to PyPI, like what we are doing for anaconda.

The advantage is that users don't need to install CMake or a C++ compiler any more. Also, it is faster to install.

To release a new version, e.g., 0.6, please do the following

1. Change
   

   kaldialign/CMakeLists.txt

   Line 17 in bc6a31f

   set(KALDIALIGN_VERSION "0.5")

   
   to

 set(KALDIALIGN_VERSION "0.6") 

2. Change
   

   kaldialign/scripts/conda/kaldialign/meta.yaml

   Line 3 in bc6a31f

   version: "0.5"

   
   to

 version: "0.6" 

git add CMakeLists.txt
git add scripts/conda/kaldialign/meta.yaml
git commit -m "Release v0.6"
git push 
git tag v0.6
git push origin v0.6

It will upload the pre-built wheels to anaconda and PyPI, magically.

I have tested the code on https://github.com/csukuangfj/kaldialign/actions/runs/3883951085

You can download the pre-built wheels and test them on your computer.

@pzelasko

I just tried to install kaldialign on my Linux server. It's really fast. No compiling is needed at all.

Will save other people's waiting time.

[pzelasko]

Yeah and people won't have the issues related to cmake etc. anymore. Very cool!!

[csukuangfj]

I have done the same thing for lilcom and other projects related to next-gen Kaldi that don't depend on PyTorch.

[csukuangfj]

And for macOS
