[tor-commits] [onionoo/master] Fix searching by hashed fingerprint.

commit b30bb951cb3e1d9b1bc3cfc479ef4aadf8bca834
Author: Karsten Loesing <karsten.loesing@xxxxxxx>

    Fix searching by hashed fingerprint.
    
    We support searches for relays by hashed fingerprint and for bridges by
    hashed hashed fingerprint.  The reason is that applications should always
    hash full fingerprints in order not to accidentally leak non-hashed bridge
    fingerprints.
    
    However, the spec is vague about searching for beginnings of hashed relay
    fingerprints and hashed hashed bridge fingerprints.  The current code did
    not support those, but it should.  This commit changes that.
