ConstDataSpan was a struct used to represent a pointer-and-length in the libcast authentication code. Replace it with ByteView which serves the same purpose. Also adds some conversion functions and a const std::vector ctor override to Span, which simplifies conversions from various other objects. These also allows various inline casts and conversion macros to be removed. Eventually I want to remove all uses of std::string and pointer-and-length for binary data in this code, but this is a step in that direction.
