switching from requests to selenium

[EvanUp]

Begin migrating library from requests to selenium. Added selenium calls (built on undetected-chromedriver) in _conduct_chromedriver_search and _send_chromedriver_request. Also added an additional step to launch chromedriver to facilitate debugging. test/selenium_test.py contains a functioning example call.

TODO: fix broken poetry command, include chromedriver update/path instructions, remove requests-specific headers
