Static classes are replaced by Engine instance singletons, this is useful for multiple instances installations since they can behave differently
Updated README.md files
Updated all packages to match the minor version, so it's easier to understand which package is matching the engine version
New Features
Added domId property to Emitters options, setting that to match a real dom element id will attach the emitter to the element (closes #2256)
Breaking Changes
The new instance singleton management is going to break the deprecated react-particles-js, but I decided to not change the major version since all the official components will continue to work as expected.
Solved performance drop issue after the refresh, closes #2809, #2815, #2936
Changes
updated fps limit default value to 120, updated all presets to have the fps limit of 120 (Chrome supports that also in Mac Pro Motion displays, Safari for now is limited to 60)
