Convert NER prediction to BIO format

Closes #229 (closed)

Tested with the provided Hennessy archive and the following script:

import logging
from pathlib import Path

from dan.bio import convert
from dan.utils import parse_tokens

logger = logging.getLogger(__name__)

ner_tokens = parse_tokens("data_hennessy/tokens.yml")

for directory in ["GT", "preds"]:
    base_output = Path(f"bio/{directory}")
    base_output.mkdir(parents=True, exist_ok=True)

    for path in Path(f"data_hennessy/{directory}").iterdir():
        logger.info(f"Converting file {path}")

        try:
            conversion = convert(path.read_text(), ner_tokens)
        except Exception as e:
            logger.error(e)
            continue

        output = base_output / path.name
        output.write_text(conversion)
