As gsl::span<> is only capable of representing ranges of elements
contiguous in memory, it is not capable of representing the majority
of Beast's buffer sequences. Examples:
Using gsl::span<> effectively type-erases the buffer sequence which is
inefficient, since it must be copied to a vector equivalent in order
to be used.

Beast never templates on the character type. All operations on
structured data (for example HTTP headers) are performed on a single
contiguous memory buffer of chars. This is done for performance
