IO scheme encoding

Hi, hope you are doing well. I'd like to ask you if you could incorporate simple IO scheme encoding in seqeval.

Thank you for this awesome library.

Hello,

I don't have a plan to implement IO scheme because it is defective in that it can't represent two entities next to each other.

Hi! I wanted to reach out because even though the IO scheme cannot identify identical entities next to each other, it is not "defective" as it has applications in production ML models which still need performance evaluations. I am building a production model now, and we are switching from IOB2 to IO for better performance on our task so it would be fantastic if you could add the IO option. Thank you!
