[examples] add paraformer results on wenetspeech+aishell4

[xingchensong]

NOTE

This is our first attempt at fine-tuning the paraformer-large to enable stream inference through a wenet-like chunk method.
Although the non-streaming results deteriorated after fine-tuning compared to before, we believe there is still significant room for improvement for paraformer-large when fine-tuned within wenet, considering this is a very initial result.

Additionally, on the same training set (wenetspeech+aishell4), we trained a conformer-large model from scratch (see experimental results in examples/aishell/s0). Comparing it with the fine-tuned results of paraformer-large, we found that the CTC results of paraformer-large consistently outperformed those of conformer-large, and the NAR results of paraformer-large were always better than the rescore of conformer-large. This is mainly due to paraformer-large having been pre-trained on 6wh industrial data, giving the model a better initialization.
