+/**
+ * Create a passthrough decoder to handle MacBinary headers added
+ * by MacLHA.
+ *
+ * The new decoder reads from the specified decoder and filters
+ * out the header. The contents of the MacBinary header must match
+ * the details from the specified file header.
+ *
+ * @param decoder      The "inner" decoder from which to read data.
+ * @param header       The file header, that the contents of the
+ *                     MacBinary header must match.
+ * @return             A new decoder, which passes through the
+ *                     contents of the inner decoder, stripping
+ *                     off the MacBinary header and truncating
+ *                     as appropriate. Both decoders must be freed
+ *                     by the caller.
