Description

Hi,

In this repo, the chrf metric implementation calls sacrebleu.corpus_chrf() with default parameters: character order 6 and word order 0. Perhaps in metric.py it would be nice to include those two optional parameters so users can specify this in task.yml, for example to facilitate chrf++ which uses word order 2?

Thanks!

Contributor guide

Research direction
Look at the chrf function in lm eval/api/metrics.py and the sacrebleu corpus chrf() parameters. Add optional arguments for character order and word order to the chrf function, then update the task.yml parsing to pass these parameters.
