public final class BinaryView
Logically the same as Binary, but the internal representation uses a view
struct that contains the string length and either the string's entire data
inline (for small strings) or an inlined prefix, an index of another buffer,
and an offset pointing to a slice in that buffer (for non-small strings).
Since it uses a variable number of data buffers, each Field with this type
must have a corresponding entry in `variadicBufferCounts`.
