databases/cego: 2.23.10 -> 2.23.11

• Added performance patch in CegoFieldValue. Values with a length up to STATICFIELDBUF size ( 100 bytes ) are handled using a static byte array. This saves expensive memory allocation calls in most cases. First very rough performances analysis has shown a performance improvement of about 5-10 percent
• The local copy logic was shifted from CegoSelect::nextGroupedTuple to CegoGroupSpace::insertTuple.
