Bump app.opendocument:odr-core-android from 6.11.0 to 6.12.0

[dependabot]

Bumps app.opendocument:odr-core-android from 6.11.0 to 6.12.0.

Release notes

Sourced from app.opendocument:odr-core-android's releases.

v6.12.0

• New Document::save(std::ostream &) and Document::save_to_memory(), which returns the saved document as an in-memory File. The path overloads are unchanged.

• The wasm binding gained edit(diff), save(), isEditable() and isSavable(), so a browser can save an edit back.

• Memory saves in the other bindings: save_to_memory() returns bytes in python, saveToMemory() byte[] in java, -saveToMemoryWithError: NSData in Objective-C.

• Two entries of the same zip document can be read at once; nothing serialises on a single lock any more.

• The zip backend is miniz/3.1.1, up from 3.0.2. Rendered output is unchanged.

• New FileType::hypertext_markup_language for html, htm, xhtml, text/html and application/xhtml+xml. Classification only: no open, no translate_html, and never detected from its bytes.

• Breaking An ods sheet stores a repeated cell once, at the range it covers, rather than once per position: SheetCell::position() reports the anchor of that range instead of the position the cell was looked up at, and Sheet::cell() hands back the same element everywhere in it.

• An ods table:number-columns-repeated beside a table:number-rows-repeated no longer inflates — the grid's own 1048576 × 1024 asked for three billion elements out of four hundred bytes.

• An xlsx <mergeCell> whose ref names more positions than the sheet has cells opens again; ref="A1:XFD1048576" used to visit all 17 billion.

• Decoding a spreadsheet costs about half the memory it did — pugixml is built in compact mode and the ods sheet index is sorted vectors rather than maps. A consumer that includes an internal header now needs PUGIXML_COMPACT, and the conan package declares it.
