* feat: add column encoding option and set it for trace span ids COMPRESSION WITH accepts encoding = 'plain' | 'delta_binary_packed'. Either disables the dictionary for the column; delta_binary_packed is limited to integer and timestamp columns. OTLP trace v1/v2 tables now create span_id and parent_span_id with plain encoding and 64KiB pages, and timestamp_end with delta_binary_packed.
