fix: remove node global (#587)

* fix: use new libp2p-crypto

* fix: remove node globals and reduce size

- adds buffer require
- adds globalThis where needed
- streaming-iterables was remove and new utils created, this will be consolidated in `ipfs-utils` and backported here to normalize all these iterator helper functions
- latency-monitor was copied inside the repo
- iso-random-stream is now used instead of node crypto
- the test `should ignore self on discovery` was moved to node only
