verify fails with dnspython==1.15.0

[Magnus Eén]

In version 1.15.0 the dns.resolver.query() method does not include the lifetime argument. And hence throw the following exception:
TypeError: query() got an unexpected keyword argument 'lifetime'

Steps to reproduce:
1. Install dnspython==1.15.0
root@ceadb57ae1bc:/# python3 -m pip install dnspython==1.15.0

2. Query the resolver with the same arguments as the dkimpy code:
>>> import dns.resolver
>>> a = dns.resolver.query('example.com', dns.rdatatype.TXT, raise_on_no_answer=False, lifetime=5)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: query() got an unexpected keyword argument 'lifetime'

Please let me know in case you need more information.

Best,
Magnus

Thanks. 1.16 has been out for over a year, so I think a reasonable resolution to this bug would be to set that as the minimum version. I don't think 1.15 compatibility is worth the complexity of dealing with it.

Thanks a lot for the quick fix Scott.
I completely agree with you. My project does actually not contain pythondns, byt only py3dns (due to pyspf). This is why it has not been updated since a long while ago. And since dkimpy chooses pythondns over pydns, I discovered this. :-)

Appreciate your work on this package!

Best,
Magnus

2019-12-31 Version 1.0.2
    - dknewkey: On posix operating systems set file permissions to 600 for
      ed25519 private key files (as is already done for RSA) (LP: #1857827)
    - Update documentation URL in README.md
    - Set minimum dnspython version to 1.16 because previous versions can not
      support the timeout parameter (LP: #1856546)
