Set a sleep for async requests
BMA API from Duniter does not handles lots of request at the same time.
With `blocks`, silkaj is requesting to know the identity of issuer of the block and send a request for all of them at the same time.
It might be Duniter’s anti-spam mechanism which prevents more requests. A sleep of 0.01 seconds between requests solves the issue.
- [x] `blocks` to get identities
- [ ] `net`:
- [x] to get leaves
- [ ] to get identities (can’t be checked on Ğ1 because it’s failing before)
