Use this command to instruct the ViVOpay reader to delete all previously set CA public keys
from within secure storage in the Crypto Chip. The keys are deleted regardless of the <RID,
Key Index> pair.
When the reader receives this command, it instructs the Crypto Chip to delete all CA public
keys. Depending on the result of this operation, the reader returns an ACK or NACK Frame.
