Changes from 2.11.2 to 2.11.3

• Frames accept now typesizes that are larger than 255 (and up to 2**31). See PyTables/PyTables#1086. Thanks to @chris-allan for the report.

• AVX512 runtime dispatching has been fixed (basically disabled) for GCC versions <= 10.

• Use typedef for blosc_timestamp_t. Thanks to Magnus Ulimoen.
