Same errormessage here with title2bib "A useful paper with hopefully unique title"

Seems this error derives from an HTTP 400 error from the crossref API:

b'{"status":"failed","message-type":"validation-failure","message":[{"type":"unknown-parameter","value":"query.title","message":"Parameter query.title has been deprecated. Please use query.bibliographic instead. See https://status.crossref.org/incidents/4y45gj63jsp4 "}]}\n'

Change the query accordingly seems to fix the issue:

# title2bib/crossref.py

def get_from_title(title, get_first=False):
    found = False
    params = {"query.bibliographic": title, "rows": 20} # change title to bibliographic
    r = find_cross_info(params)
    items = r.json()["message"]["items"]

If this is the correct way to fix it I can make a pull request later.
