GHSA-C85P-XXJJ-2R75 Excelize ColumnNameToNumber: int64 overflow yields an out-of-domain coordinate with nil error, causing negative slice index panic on r="0" rows

Summary ColumnNameToNumber lib.go:220-237 accumulates the bijective base-26 value of a column name in an int64 with only an upper-bound check col MaxColumns applied after the loop and no overflow detection. A 14-letter column name whose true value is 3·2⁶⁴ — e.g. VGWQHXLSDVIKWV — wraps to col = 0...
