  Clean up the functions in loadimage.h/cpp.
  
  * Capitalize the function names to fit the style guide.
  * Use explicit sizes in the function names to avoid any confusion about
    input or output sizes.
  * Use explicit sized types in the functions to avoid potential issues on
    new platforms since a lot of bit-twiddling is used.
  * Use size_t for all sizes.
  * Use uint8_t for all binary data for input and output data so that pointer
    arithmetic is much easier.
  * Move templated function definitions into an .inl file so that
    loadimage.h looks as clean as possible.
