Read only the cells the category levels use and cut the category dimension
at the per-series cap, so a multi-level axis keeps all its levels.

A chart keeps at most 2,000,000 series x points (every series and the
categories keep their first points), 16 trendlines per chart; columns and
bars narrower than 0.25 px are merged per pixel column; series references
are cut after the rows that can matter before calc evaluates them; the
moving average is linear; fit_trendline allocates no Vec per point;
render borrows clean data instead of cloning it.
