Support for non ascii

[minmin2104]

Hi, I was using botasaurus when I notice it doesn't properly output my french character to the json file. I did some reading and found this in utils.py

def write_json(data, path,  indent=4):
    with open(path, 'w', encoding="utf-8") as fp:
        json.dump(data, fp, indent=indent)

Afaik, json dump function has an option to modify ensure_ascii to either False or True. is there a feature of this that I didn't found? if no, can I create a PR to have the option of modifying ensure_ascii?

Thanks in advance
