Save APKs for each release in a separate directory.
Huggingface requires that each directory cannot contain more than 1000 files.
Since we have so many tts models and for each model we need to build APKs of 4 different ABIs,
it is a workaround for the huggingface's constraint by placing them into separate directories for different releases.
