Bumps idna from 2.7 to 3.0.

Changelog

Sourced from idna's changelog.

3.0 (2021-01-01)

• Python 2 is no longer supported (the 2.x branch supports Python 2, use "idna<3" in your requirements file if you need Python 2 support)
• Support for V2 UTS 46 test vectors.

2.10 (2020-06-27)

• Update to Unicode 13.0.0.
• Throws a more specific exception if "xn--" is provided as a label.
• This is expected to be the last version that supports Python 2.

2.9 (2020-02-16)

• Update to Unicode 12.1.0.
• Prohibit A-labels ending with a hyphen (Thanks, Julien Bernard!)
• Future-proofing: Test on Python 3.7 and 3.8, don't immediately fail should Python 4 come along.
• Made BSD 3-clause license clearer

2.8 (2018-12-04)

• Update to Unicode 11.0.0.
• Provide more specific exceptions for some malformed labels.
