Feature: Hyperformula

[Corbe30]

• Replace formula-parser with Hyperformula

Fixes:

• “用一个forked handsontable/formula-parser 来处理公式计算。”公式引擎Bug较多！ #552
  • =IF(A1="","","YES") null should be same as empty cell
  • IF(A1,B1 * B2,B3 * B4) false statement evaluates even when not required
• IFERROR function doesn't work #461

Performance:

• ~50% improvement in edit operations on large sheets (850ms -> 440ms)

Existing unreported bugs resolved:

• incorrect patches sent in add/delete sheet
• insert/delete row/col redo had incorrect formula cached

Optimized:

• formulaHelper.ts:246 - removed cloneDeep by refreshing formulaObject.color
