Read and write hexadecimal floating point numbers. Provides a quasiquoter for entering hex-float literals, and a function for printing them in hexadecimal. See: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf, pages 57-58. We slightly diverge from the standard and do not allow for the "floating-suffix," as the type inference of Haskell makes this unnecessary.
