* Add craft-math: the equation tree with OMML, MathML, LaTeX and UnicodeMath
The math tree, LaTeX, linear-format, symbol and tree-walk modules come
from craft-wordmodel (storytold/craft-libs#963, WordCraft's crates/doc at
07f97737) unchanged, with the run colour (Rgb) and the symbol-font tables
they use. MathML is WordCraft's crates/formats/src/mathml.rs and OMML is
WordCraft's crates/docx/src/read/math.rs and write/math.rs (06c2ae6f /
07f97737), moved onto craft-xml. The HTML-specific MathML tests stay in
WordCraft; the rest moved with the code.
mathml::parse and omml::parse/read_str/write_str are new: string entry
points for callers that have no tree of their own.
* craft-math: read MathLive's and other spellings of LaTeX math commands
\abs{...} (an absolute value), \lvert \rvert \lVert \rVert, \nparallel,
\backprime, \infinity, \cross, \differentialD, \exponentialE and
\imaginaryI (MathLive's d, upright e and i), \emph, \textsf, \hbox,
\mathnormal and \underleftarrow / \underrightarrow /
\underleftrightarrow were unknown and read as literal text. They are read
as equaSHion's typed-input parser reads them (storytold/craft-libs#29).
* craft-math: equaSHion's equation corpus as test data
corpus/equations.tsv, corpus/latex.tsv and the OMML samples of
storytold/craft-libs#29 (7a6ef6b9), unmodified.
* craft-math: corpus round trips, GridCraft's OMML cases, entry points and limits tested; README
The corpus equations go through OMML, MathML and LaTeX and back; the OMML
samples are written back as kept and from the tree. GridCraft's OMML to
LaTeX test cases (crates/xlsx/src/omml.rs) give LaTeX that reads back the
same through the tree. omml::parse and read_str are tested against other
prefixes, the strict namespace, kept OMML, junk, the element cap and deep
nesting.
