Optimize repo size

[xavier506]

Remove large unused git objects to reduce repo size.

The largest file is an idx called something like .git/objects/pack-f8... that has a large object of over 70mb thats making cloninfg the repo really slow.

we need to remove that object from the history también.

@danazkari I made a fork and try with
https://rtyley.github.io/bfg-repo-cleaner/ and everything is ok but in the eosrate repo I found an error.

! [remote rejected] refs/pull/94/head -> refs/pull/94/head (deny updating a hidden ref)

rtyley/bfg-repo-cleaner#36

Maybe we can try
