+ * S4<length><address><name>,<checksum>

+ * is the record type. Where:

+ * 2 data record with 24-bit address
+ * 3 data record with 32-bit address
+ * 4 symbol record (LSI extension)
+ * 5 number of data records in preceeding block
+ * 6 unused
+ * 7 ending record for S3 records
+ * 8 ending record for S2 records
+ * 9 ending record for S1 records
+ *
+ * length
+ * is two hex characters. This defines the length of the

+ enough room in the output buffer), next_in is updated and processing
+ will resume at this point for the next call of inflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. inflate() always provides as much output as possible
+ (until there is no more input data or no more space in the output buffer).
+
+ Before the call of inflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming
+ more output, and updating the next_* and avail_* values accordingly.
+ The application can consume the uncompressed output when it wants, for
+ example when the output buffer is full (avail_out == 0), or after each
+ call of inflate().
+
+ If the parameter flush is set to Z_PARTIAL_FLUSH or Z_PACKET_FLUSH,

+ flushing behavior of inflate is not specified for values of the flush
+ parameter other than Z_PARTIAL_FLUSH, Z_PACKET_FLUSH or Z_FINISH, but the
+ current implementation actually flushes as much output as possible
+ anyway. For Z_PACKET_FLUSH, inflate checks that once all the input data
+ has been consumed, it is expecting to see the length field of a stored
+ block; if not, it returns Z_DATA_ERROR.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step

+ Z_FINISH. In this case all pending input is processed and all pending
+ output is flushed; avail_out must be large enough to hold all the
+ uncompressed data. (The size of the uncompressed data may have been saved
+ by the compressor for this purpose.) The next operation on this stream must
+ be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+ is never required, but can be used to inform inflate that a faster routine
+ may be used for the single inflate() call.
+

+ processed or more output produced), Z_STREAM_END if the end of the
+ compressed data has been reached and all uncompressed output has been
+ produced, Z_DATA_ERROR if the input data was corrupted, Z_STREAM_ERROR if
+ the stream structure was inconsistent (for example if next_in or next_out
