Entropy of generated xpubs

[pythcoiner]

In Joinstr::new_peer() the lib generate npub that will be used to auth to the pool, is the entropy of the key good enough? is there some some possible footgun about how we generate the key?

Keechain is using some sources of entropy for mnemonic, maybe we could do the same?
