Dylan M. Taylor baf6bd58f0 Add craft-flow: the flow model the text formats map to (#1025)
* Add craft-wordmodel: WordCraft's document model without its editing code

WordCraft's crates/doc (wordcraft-doc, at 07f97737) moved as it is, so the DOCX,
RTF, ODT and other text-format crates can read into and write from one model.
Module paths, type names and serde attributes are unchanged: an app that
re-exports the crate keeps its native file format.

Left in the app: range editing (edit.rs), IME text and equation editing. Not
model, and already in craft-libs: code pages (craft-rtf), the ZIP entry-count
check (craft-opc), the compound-file guard (craft-cfb). The paragraph walks
moved to walk.rs and the unit helpers of wordcraft-geom to geom.rs.

* craft-wordmodel: math_tree, the arguments of an equation node and a walk over its runs

The DOCX reader and writer walk an equation's runs. The walk and the child
accessors it uses were in WordCraft's equation editor (math_edit.rs), which
stays in the app; they are structure, not editing.

* craft-wordmodel: keep the document operations (edit.rs) with the model

The DOCX and RTF readers use them: alternative-format chunks are merged into
a document with adopt_blocks, and a reader formats ranges with format_range
and inserts objects. They operate on the document, not on a view, so they
belong beside it. The tests that drove them come back with them; the
paragraph walks stay in walk.rs and edit re-exports them.

base64 0.23, as WordCraft and craft-offcrypto use.

* Add craft-flow: the flow model the text formats map to, on craft-wordmodel

WordCraft's crates/formats/src/model (07f97737) moved as it is: Flow,
FBlock, Para, Inline, Fmt, tables and cells, pictures, to_doc and
from_doc, picture sniffing, colours, base64 and the Dropped report. Only
the paths changed (wordcraft_doc is craft_wordmodel); the report helpers
are public so the format crates can call them; the image re-encoding
helper stays with WordCraft's RTF writer.
