craft-xlsx: pictures in cells and dynamic-array metadata * craft-xlsx: read parts with canonical prefixes so kept trees can be written back The part layer read every part by local name, so extLst children (x14:, xr:, xm:), mc:AlternateContent and r:id lost their namespaces and could not be written back. Parts are now read with one fixed prefix per namespace (the main namespace unprefixed), mc:Ignorable and mc:Choice/@Requires are rewritten to match, and ns::declare prepares a kept tree for writing. craft-xml: a namespace listed with the empty prefix reads unprefixed. * craft-xlsx: write SpreadsheetML workbooks (Document read and write) Document holds a whole workbook: the workbook part, shared strings, styles, each worksheet's rows and the rest of its part, and every other part kept as bytes. write regenerates the workbook part, worksheets, shared strings and styles from the model, keeps unknown children in place (schema order for regenerated ones), keeps part names and relationship ids, and writes kept parts unchanged. Writers: Styles::to_xml and to_el for each table entry, StringItem::to_el (phonetic runs checked as on reading), SheetPart::to_xml with rows streamed, Workbook::to_el, XlsxKind. Row and DefinedName keep their other attributes; CellStyle reads iLevel. craft-opc: LazyPackage::canonical gives a part's stored name. * craft-xlsx: typed worksheet features and comments, written back SheetPart::features lifts sheet views, print setup, data validation, conditional formats, hyperlinks and the legacy drawing into types that mirror their elements (optional attributes, unnamed ones kept) and writes them in schema order. Comments come from the comments part, note shapes from the VML drawing; a sheet that gains comments without a VML drawing gets one. A hyperlink to a new URL gets its own relationship. craft-sheet: Range derives Default. * craft-xlsx: drawings, charts and the theme on craft-drawingml Drawing reads a sheet's xdr:wsDr into anchors with typed placements and objects kept as written; Anchor gives the object's kind, properties, chart or image relationship and xfrm. Package::drawing, Package::chart (c: and cx: parts through craft-drawingml) and Package::theme. Document worksheets hold their drawing part, regenerated with its relationships kept by id; add_chart and add_picture add new chart parts (chartEx behind mc:AlternateContent) and images with their anchors. More drawing namespaces get prefixes (a16, asvg, aink, am3d, cx1-cx4, dgm). * craft-xlsx: tables (ListObjects) read and written back Table mirrors CT_Table: every attribute, columns with calculated and totals formulas, the style info, autoFilter/sortState/extensions kept as written. Package::tables reads a sheet's table parts; Document worksheets hold them as TableParts, regenerated with their relationships and tableParts entries. Part names a document keeps are reserved before new parts are named, so a new part never takes a name a later sheet keeps. * craft-xlsx: PivotTables (caches, records, tables) read and written Typed pivot cache definitions (source, fields, shared items, grouping), streamed cache records and PivotTable definitions (location, fields and items, axes, page and data fields, style), with every unmodelled child and attribute kept. Workbook::pivot_caches lifts pivotCaches. A Document holds caches and tables and regenerates their parts, relationships and pivotCaches entries; an OLAP cache or a table on one stays a kept part. SharedItems::describe gives Excel's shared-item flags and records_xml writes a records part, after GridCraft's pivot writer. * craft-xlsx: pictures in cells and dynamic-array metadata Package::cell_pictures follows a cell's vm through the value and future metadata to its _localImage rich value and image, bounded and lenient as GridCraft's richdata.rs reads it. Document::add_cell_metadata writes the metadata part (XLDAPR for dynamic arrays, XLRICHVALUE for pictures), the rich-value parts and the images as GridCraft writes them.
