Local file URL validation #481
Description
Fails to validate URL for local file:
from validators import url
url("file:///var/www") # ValidationError(func=url, args={'value': 'file:///var/www'})Excpected True, because this URL type standartizated in RFC 8089.
Error in _validate_netloc() function. It expected domain like var.com, but see directory var.
ValidationError(
func=hostname,
args={'value': 'var', 'skip_ipv6_addr': True, 'skip_ipv4_addr': False, 'may_have_port': True, 'maybe_simple': False, 'consider_tld': False, 'private': None, 'rfc_1034': False, 'rfc_2782': False}
)May be we should skip netloc validation in some cases like file and add file scheme in _validate_scheme() function.
Works this code, but is it correct behaviour for common URL scheme?
from validators import url
url("file:///var/www", simple_host = True, validate_scheme = lambda x: x == "file") # True

Fixed by #483:
url()now acceptsfile://URLs per RFC 8089 (an empty authority orlocalhost). Thanks for the report!
