<MSG> Remove 'Contributors' section from README, upgrade pdoc (#67)

* Remove 'Contributors' section from README

Removes a dependency on an external image service. GitHub now lists
contributors in the repo's sidebar, which is better user attribution
than profile images and a link to graphs/contributors.

* Upgrade pdoc to fix build issue
