import
Imports a BIP340 private key (importer).
WARNING: Private key import is an advanced feature. Shares generated from imported private keys have the risk of the private key being compromised if it's not properly deleted after the import operation.
This is the method that the importing party (the one in possession of the private key) should use to distribute shares of the private key to a threshold-of-numParties quorum.
Return
KeyGen object containing the public key and secret share for the imported keypair
Parameters
The UUID of the import room
The threshold of the new quorum (value in range 1..65535)
The private key to be imported (a hex string of length 64)
Contains the keygenSecret for the importing party
The keygenIds of all parties that will be part of the new quorum
