* Add craft-sheet: the cell positions, values and tables the spreadsheet formats share craft-xls carried its own CellRef, Range, Value, CellError, Visibility, sheet-name quoting, built-in number format table and indexed palette. craft-xlsx and craft-ods need the same ones, so they move to a crate with no dependencies and craft-xls re-exports them: an application gets one Value and one CellRef whichever file it read. Added on the way: A1 parsing (CellRef::parse, Range::parse), Range::count and a1, CellError::parse and the newer error values SpreadsheetML stores as text, builtin_format_id for writers. * Add craft-xlsx: the part layer of XLSX and XLSB workbooks Package::open finds the workbook part through craft-opc and reads the workbook part, shared strings (runs and phonetic readings), the styles tables as indexed tables, and a worksheet's rows one at a time with the rest of the part as a tree. Binary workbooks give the same workbook, strings, rows and merged cells from their records. Every other part stays reachable through Package::opc. From GridCraft crates/xlsx (7e0d96d7): read.rs, sheet_read.rs, styles.rs, xml.rs (string items, xstring escapes), xlsb.rs and its tests, split from GridCraft's document model. * craft-xlsx: XLSB opens up to 4 million cells, records counted once over the workbook Binary workbooks over 1 million cells were refused, a quarter of what .xls allows, and an allowance of 5 million records per part refused ordinary files: Excel writes four records per non-empty row besides the cells, and one BrtCellBlank for every formatted empty cell. Cells are now 4 million over the workbook (also the most shared strings), text 256 MiB, and records 40 million for every part together, as in craft-xls.
