About Whisper finetuning on a out-of-vocabulary language datset
### Feature request

Hello!
I am working on Whisper, and I want to finetune the model on _Amharic_ in OpenASR20 dataset. As far as I know,  _Amharic_ is not one of the languages participating in Whisper training. If I want to finetune the model on _Amharic_, what should I do?
Looking forward to your reply! Thank you!
