Allow typing-extensions version 4.x (#107)

Currently, `[tool.poetry.dependencies]` is configured to only allow `typing-extensions` with major version `3`. `typing-extensions` was bumped to version `4`; I believe the only significant change is dropping Python 3.5 support, which is already unsupported by other dependencies. Allow version 4 to be used to avoid unnecessary package conflicts when installed in existing virtualenvs.
