[Feature request] Implement ExpectedConditions from Selenium

[Derpitron]

One feature I really miss and need from Selenium is Expected Conditions,
https://www.selenium.dev/selenium/docs/api/java/org/openqa/selenium/support/ui/ExpectedConditions.html
https://www.selenium.dev/documentation/webdriver/support_features/expected_conditions/

In my case, implementing this using zendriver without having access to this is a real pain. To find out if a button is clickable, in Selenium I could just wait for the element to be clickable. With thiis I have to manually find and maintain the correct HTML class names per button state.

If you could implement this It'd be a real QoL thing for people coming from the webdriver world. I couldn't find any analogous method in zendriver or zerodriver from the docs.

Thanks to you guys and ultrafunkamsterdam for maintaining these libraries!
