Freeze panes

The Excel Freeze Panes corner on a plain <SvGrid>: the Account and Owner columns stay pinned while you scroll across a full year of months, and the sticky column-letter + row-number headers stay put as you scroll down. HyperFormula keeps each row total (column O) and the bottom Total row live as you edit any month. Pinning those two columns is one prop: initialColumnPinning.
