func DecryptETag 

func DecryptETag(key crypto.ObjectKey, object ObjectInfo) (string, error)

DecryptETag decrypts the ETag that is part of given object with the given object encryption key.

However, DecryptETag does not try to decrypt the ETag if it consists of a 128 bit hex value (32 hex chars) and exactly one '-' followed by a 32-bit number.
