/*!
* @brief Allocate and initialize an object for creation of an Enveloped message object
*
* Allocate and initialize the object used to create a COSE Enveloped message object.
* Supported flags are:
* COSE_INIT_FLAG_DETACHED_CONTENT - content is not part of the message
* COSE_INIT_NO_CBOR_FLAG - Do not emit the leading CBOR tag on the message.
*
* See the notes on the memory model for the use of the context variable.
* Applications need to free the returned handle before deallocating the
* memory block that it was wrapped in for correct handle checking.
*
* @param flags Set of initialization flags from the COSE_INIT_FLAGS enum
* @param context CN_CBOR context allocator struture
* @param perr Location to return error specific information
* @returns handle to the newly allocated object
