Restore copyright notice in main module

[jayaddison]

With reference to this note from @pwdyson re: the removal of this notice:

Thanks James for drawing my attention to this. The copyright and my name should not be removed. Please put it back.

This reverts commit e640d3a.

cc @jaraco - this is a small copyright notice adjustment, co-ordinated with Paul.

Thanks for the ping. Let's first start with an issue where we can discuss the implications and tradeoffs.

[pwdyson]

Please restore my name and copyright notice. Then we can discuss any changes.

Quoting from https://www.linuxfoundation.org/blog/blog/copyright-notices-in-open-source-software-projects :

Don’t change someone else’s copyright notice without their permission

You should not change or remove someone else’s copyright notice unless they have expressly (in writing) permitted you to do so. This includes third parties’ notices in pre-existing code.

See #197 (comment), where I lay out the plan.
