Row queries drop whether a value came from a formula and how the cell is styled, which callers need when importing hand-edited sheets.

Reject every invalid explicit cell reference.
TryParseCellReference initializes referenceColumn to 0 and can return false with a valid-range column. For example, A1? leaves the column as 1, so the current branch uses the sequential column instead of rejecting aR.
Throw for every nonempty aR that fails parsing. Keep the sequential fallback only for a missing reference.

Part of #239
Row queries return only cached values, so callers can't tell whether a value came from a formula, and cell styling is lost. This adds
QueryCells/QueryCellsAsync, which yields each stored cell with its formula, font color and number format. Existing queries are unchanged.HasFormula = truewithFormula = null, since only the anchor cell stores the text.FontColoris a newExcelColorrather than theSystem.Drawing.Colorused byOpenXmlCellStyle(Add deferred cell style updates #1013), because theme colors and tints can't be represented without resolving the theme.Tested against a workbook saved by Excel 16 with shared formulas, theme colors with tints and custom number formats.
