This type is a type designed to carry binary data that appears in various

BSON's generic binary subtype. This type is NOT a part of standard JSON and
exists solely for compatibility with these binary types. As such, it is

@brief an internal type for a backed binary type
This type is designed to be `binary_t` but with the subtype implementation
detail. This type exists so that the user does not have to specify a struct
his- or herself with a specific naming scheme in order to override the
binary type. I.e. it's for ease of use.
