* 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).
