Same NameEmail field instances are not equal

Bug

Output of python -c "import pydantic.utils; print(pydantic.utils.version_info())":

             pydantic version: 1.5.1
            pydantic compiled: True
                 install path: /Users/***/.local/share/virtualenvs/tempenv-42b2286175873/lib/python3.7/site-packages/pydantic
               python version: 3.7.4 (default, Jul 22 2019, 11:21:52)  [Clang 10.0.1 (clang-1001.0.46.4)]

I'm assuming that equality should be enforced on field types such as NameEmail. At the moment it seems that instances that appear to be equal are generating different hashes. Unsure if this is desired, but I would argue it shouldn't be.

import pydantic

# will raise an AssertionError
assert pydantic.NameEmail("test", "test@test.com") == pydantic.NameEmail("test", "test@test.com")

Thanks for reporting.

Happy to accept a PR to add a proper __eq__ method to NameEmail
