// FromBytes creates a new temporary file in the directory dir with a name beginning with prefix,
// opens the file for reading and writing, writes the provided data into it
// and returns seeks the underlying file object to 0.
//
// If dir is the empty string, TempFile uses the default directory for temporary files (see os.TempDir).
// Multiple programs calling TempFile simultaneously will not choose the same file.
// The caller can use f.Name() to find the pathname of the file.
// It is the caller's responsibility to remove the file when no longer needed.
