// Parse a SPIR-V module, and extracts all HLSL source code from it.
// This function doesn't lift the SPIR-V code, but only relies on debug symbols.
// This means if the compiler didn't include some files, they won't show up.
//
// Returns a map of <filename, source_code> extracted from it.
// - `binary`: a vector containing the whole SPIR-V binary to extract source
// from.
// - `output`: <filename, source_code> mapping, mapping each filename
//            (if defined) to its code.
//
// Returns `true` if the extraction succeeded, `false` otherwise.
// `output` value is undefined if `false` is returned.
