BIP340 - Refresh a key share

POST 
/bip340/refresh

Used for refreshing the secret material of all parties without altering the public key at all. Returns a new key_id for the new share but does not delete the old key_id. It is highly recommended to delete the old key_id after the refresh operation is successful.

The motivation for using refresh is to enhance security by switching the secret key material frequently, this means that an adversary will need to compromise multiple devices at the same time in order to compromise the private key.
