* 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-ods: OpenDocument spreadsheet tables on craft-odf read() checks the spreadsheet mimetype, refuses an encrypted package, and reads the tables of content.xml into sheets of cells that keep the file's terms: value type, the raw value, displayed text, formula text, style name, covered cells, with repeats expanded and merged ranges. Cell::value() gives the shown value, dates and durations as serial numbers. From GridCraft crates/xlsx/src/ods.rs and its tests (7e0d96d7), split from GridCraft's document model and moved onto craft-odf and craft-xml's pull reader. Options::only_sheet covers WordCraft's reader of one chosen sheet.
