Thanks for updating!

FYI, I just added this LLA algorithm to the PublicKey class in [1] with 
three caveats:

  * it allows for injection into an arbitrary IPv6 or IPv4 address space 
(default is the LLA/10 that wg-lla uses)
  * it fails if the generated address is the network address or 
broadcast address of the provided address space
  * it allows for an optional blake2b key, to mix the addresses if 
desired (default is no secret, which produces the same addresses as wg-lla)
