Support conda install

[csukuangfj]

Fixes #7

Assume that you have set up the secret KALDIALIGN_CONDA_TOKEN, the steps to release a package to conda is:

(1)

git pull
git checkout -b release-v0.5
vim CMakeLists.txt
# Change KALDIALING_VERSION, e.g., 0.5

vim scripts/conda/kaldialign/meta.yaml
# Change version, e.g., 0.5

git add CMakeLists.txt
git add scripts/conda/kaldialign/meta.yaml
git commit -m "Release v0.5"
git push -u origin release-v0.5

(2) Create a pull-request based on release-v0.5 branch and merge it to the main branch
(3)

git checkout main
git pull
git tag v0.5
git push origin v0.5 # This command automagically triggers github actions to release a new version to conda

Note that you can find the package files at

https://anaconda.org/kaldialign/kaldialign/files

and you can install kaldialign using

conda install -c kaldialign kaldialign

It supports macOS, Linux, and Windows with Python 3.6, 3.7, 3.8, 3.9, and 3.10.

For testing purpose, you can install kaldialign using

conda install -c k2-fsa-2 kaldialign
