Reduce git repo size as historical data increases size of this repo

[fawazahmed0]

jsdelivr caches the git repo , after someone requests the url through jsdelivr.

So curl all the urls for caching and then delete the date from git repo and run BFG cleanerto reduce git repo size, to avoid burden on github

or by adding date tag, we can access previous commits of same folder, without having to make datewise folder, but this will cause api design to change for accessing historical data
