pwhash.verify raises TypeError

[darkwyrm]

Pardon me if I'm completely missing something here, but I stumbled upon something which genuinely looks to me like a bug. Steps to reproduce:

>>> import nacl.pwhash
>>> nacl.pwhash.verify('foo','bar')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/owner/.local/lib/python3.6/site-packages/nacl/pwhash/__init__.py", line 65, in verify
    if password_hash.startswith(argon2id.STRPREFIX):
TypeError: startswith first arg must be str or a tuple of str, not bytes

I stepped through with pdb and discovered that argon2id.STRPREFIX is of type bytes instead of string. I ran across this on Ubuntu 18.04 with Python 3.6.9 but also with the current Windows build on Windows 10. In both instances, pynacl 1.3.0 was installed using pip.

The arguments to verify() should be bytes instances, not str.
