[bitcoin-dev] BIP CPRKV: Check private key verify

There was some discussion on the bitcointalk forums about using CLTV for
cross chain transfers.

Many altcoins don't support CLTV, so transfers to those coins cannot be
made secure.

I created a protocol.  It uses on cut and choose to allow commitments to
publish private keys, but it is clunky and not entirely secure.

I created a BIP draft for an opcode which would allow outputs to be locked
unless a private key was published that matches a given public key.
