Fix base64 decoding

This limits the number of bytes read, so that the entire stream is not
decoded for every plane.  It also removes the extra encoding step in
favor of trimming the already-encoded base64 string at the first "<".
Set the encoding to ASCII to handle units.

The sample files should now work.
