big update! I integrate the latest updates of shell scripts, optimize the implementation of sae and fix some bugs.

fix the implementation of the relative position encoding in conformer, optimize the code of ctc loss

I reformat the code, implement the intermedia ctc with adapter and the ctc decoding.

Cumulative updates. I mainly optimize the shell scripts and support the new benchmarks. It is more friendly to MT researchers (also including me). I also improve the code. Of course, old problems still remain and new problems arise. Just keep coding.

I have wanted to do this for a long time!

I optimize the implementation of the speech-to-text tasks. As always, I update the shell scripts and YAML configures for easy training.
There may be some bugs. So, the follow-up update is coming!
