Allow md5hash to function in fips environments

[trevor-scale]

Many secure environments disable the hashlib.md5 function because it is insecure, this causes the line below to fail making dateparser unusable in these environments:

dateparser/dateparser/conf.py

Line 52 in 02bd2e5

return hashlib.md5("".join(keys).encode("utf-8")).hexdigest()

This is remedied by replacing that line with return hashlib.new("md5", "".join(keys).encode("utf-8"), usedforsecurity=False).hexdigest() which appropriately bypasses the fips security check because dateparser is not using the md5 hash for security applications.

Corresponding issue: #1258

I posted this in #1258 as well. Change usedforsecurity=True to usedforsecurity=False. The suggestion/example provided in issue 1258 was to use hashlib.new but it also included the full command which had usedforsecurity=True to test a failure when using FIPS compliant encryptions/hashes/etc. My apologies for not being clear.

Thanks for catching this wasn't looking closely when I copy-pasted haha. Will update now!
