Performance

This version contains major performance improvements in the following functions:

• Floki.filter_out/2.
• Floki.find/2 - with some improvements to specific selectors, like classes and attribute selectors.
• Floki.text/2.

Those functions are not only faster, but are now using less memory. Please check the PRs related to this release if you want to better understand the numbers.

• Speed up do_classes_matches? - [#649]
• Make filter_out faster - [#650]
• Speed up attribute lookup - [#651]
• Enable tuple traversal optimization for multiple selectors - [#652]
• Optimize HTMLTree.to_tuple conversion using Enum.reduce - [#657] (github.com)
• Optimize Finder.get_descendant_ids/2 memory usage and speed - [#660]
• Optimize Finder.get_siblings/2 memory usage and speed - [#663]
• Optimize FlatText.get/3 memory usage and speed - [#664] (github.com)
• Optimize class matching in Floki.Selector - [#665] (github.com)

All the improvements in this version were made by Barna Kovacs - @preciz, so shout out and thanks to him!
