add tags for each released version

[maruilian11]

hi, recently we want to add your lib on https://cdnjs.com, we use npm auto-update or git auto-update(depending on git tags) to add every released version, so could you please consider adding tags for every released version?

thank you very much!

cdnjs/cdnjs#6993

sorry, not notice this lib can be downloaded by npm package, we have added it with npm auto-update.
