This PR fixes a small bug with RLE decompression. The low order control bits need to be used for control code 0x70, similarly to how they are used with 0x60.
I also added a check that the decompressed result has the expected length.
I confirmed that the mixed.sas7bdat file appended to issue #21 is read correctly after making this change (I compared it to direct export from SAS).
