Release develop branch improvements

[absar]

Hi @HayesGordon thank you for this package.
I see you have done many improvements in develop branch, specially delta time without which particle speed and quantity is not consistent on different fps devices, would be nice if you release the changes and maybe with updated dependencies and wider dart lang version constraints e.g. sdk: ">=2.17.0 <4.0.0" instead of sdk: ">=2.17.0 <3.0.0"
