Take screenshot of webelement

[obonyojimmy]

Id like to propose a function that extends webelements struct and can take screenshot just as the page struct does ... anyone with example please share

Apologies for the delay.

This seems very straightforward to implement: https://w3c.github.io/webdriver/webdriver-spec.html#take-element-screenshot

Happy to accept a PR.

At the api package level, you'd want to implement GetScreenshot on api.Element.

Then you'd want to expose it at the agouti package level, on a Selection. It could produce a screenshot for each element selected, or fail if you don't have exactly one element selected.

Closing this in favor of #111.
