Supporting transforms for Floki nodes!

[bobjflong]

Hi! Thanks so much for Floki!

I have a need to transform Floki nodes. For example, to turn all relative links into absolute links:

html = "<p><a href='/foo'>click!</a></p>"
Floki.transform(html, "a", fn({"a", [href: x], xs}) -> {"a", URI.merge("https://base.com", x), xs} end)
# => [{"p", [], [{"a", [{"href", "https://base.com/foo"}], ["click!"]}]}]

Instead of requiring the implementation of a recursive search, do you think there is space in the Floki API for a transform function like above? I'd be up for cutting a PR myself. Just wondering if you have any thoughts.

Hi @bobjflong! Thank you for the PR and the issue! 😃 I couldn't check this with attention yet, but I will check soon. :)
