v0.5.0

Qlik Sense-compatible QVD output

QVD files generated by qvdrs are now binary-identical to Qlik Sense output (verified by MD5 hash comparison).

Changes

• Symbol types: Int/Double instead of DualInt/DualDouble — 2× smaller symbol tables
• NumberFormat: proper ASCII, INTEGER, REAL, DATE, TIMESTAMP types with correct formatting
• Tags: $ascii, $text, $numeric, $integer, $timestamp, $date
• BitWidth: reserves NULL sentinel (bits_needed(num_symbols + 1)) — Qlik convention
• BitOffset: sorted by descending width for optimal packing
• NULL representation: bias=0, NULL index = num_symbols (Qlik convention)
• XML header: always includes Lineage, TableTags, ProfilingData elements
• normalize(): new method to auto-fix any QvdTable for maximum Qlik compatibility
• README: rewritten with comprehensive examples — DuckDB, Database→QVD, CSV/Excel→QVD
