gugarosa/opytimizer: v3.0.0

Changelog Description Welcome to v3.0.0 release. In this release, we have revamped the whole library, rewriting base packages, such as agent, function, node and space, as well as implementing new features, such as callbacks and a better Opytimizer bundler. Additionally, we have rewritten every optimizer and their tests, removing more than 2.5k lines that were tagged as "repeatable". Furthermore, we have removed excessive commentaries to provide a cleaner reading and have rewritten every example to include the newest features. Please take a while to check our most important advancements and read the docs at: opytimizer.readthedocs.io Optimization checkpoints; Multiple runnings; Resuming from file. Note that this is a major release and we expect everyone to update their corresponding packages, as this update will not work with v2.x.x versions. Includes (or changes) opytimize
