How to inference on other <midi, text> files using the opencpop phone_set.json?

Hi, thanks for the great work!
I want to inference on my own <midi, text> files. I generated the corresponding meta.json and tried to binarize it. But the binarizer can only generate phone_set.json based on the input files, which will be incompatible with the pretrained checkpoint (since it was pretrained on opencpop with opencpop phone_set.json). A solution is to preprocess the customized testset with the original opencpop meta.json to obtain the full phone_set.json (i.e., the same phoneme dict). However, it is too inconvenient to do that thing.

Start with the binarizer and the generation of phone_set.json from meta.json; compare the custom test-set path with the Opencpop phone_set.json expected by the pretrained checkpoint. Done means custom MIDI and text files can be prepared for inference without first processing the original Opencpop meta.json.
