feat(formulas): create new Formula Editor plugin

[ghiscoding]

Similar implement to Ag-Grid Formulas which is basically to be able use Excel spreadsheet formulas in any grids. This will be an opt-in plugin (external resource) and after installation the user will simply need to add allowFormula to whichever column definition

TODOs

• working POC
• export to Excel with formulas
• full unit tests coverage
• Cypress E2E tests
• better showing of formula cell selected and cell range selected
• support Custom Functions
  • note: implemented already but on the export side, it is only supported by latest Office 365 via (Lambda functions)
• function intellisense isn't working in the middle of the formula
  • formula cell selection are being inversed when adding a sum in the middle of the formula
    • when fixed, we need Cypress tests to avoid future regression
  • dark theme has multiple unused SASS variables that we might need
• should we use textarea instead of input for the cell formula editor
  • I think we should simply make the editor as 100% width like any typical editor
• What should we do when offset introduced?
  • not currently working with Grouping
  • issues with Column Reorder and/or Hiding a column
  • it could work with REF(COLUMN("price"),ROW("1")) but that is a lot to type instead of C1, perhaps we could do mapping behind the scene and update the mapping when offset is introduced (e.g. column reorder, grouping)?
  • and actually Ag-Grid stores all formulas with ref/row as per their docs:

Stored formulas:
Key: a_01-total, Formula: =REF(COLUMN("price"),ROW("a_01"))*REF(COLUMN("quantity"),ROW("a_01"))
Key: o_02-total, Formula: =REF(COLUMN("price"),ROW("o_02"))*REF(COLUMN("quantity"),ROW("o_02"))

• does a formula ref (e.g. REF(COLUMN("price"),ROW("1"))) actually works with Excel export?
• can we have more highlighted styling for the selected cell(s) that we choose from the formula editor (perhaps double bg opacity), we currently only see the caret on bottom right corner
• what about Grid State/Preset?
• current range selection in Hybrid Selection model only works if we expand the drag further down, but it doesn't work correctly when decreasing the range or going up (need fixes in the hybrid selection model)
• dragging a formula cell should replicate formula to cell targets (same as Excel) using cell selection "drag-fill" feature
• wonder if we should also include the calculated columns which is Excel formulas but at the column level (e.g. calculatedExpression: '[revenue] - [cost]' where [revenue] is the column id in square bracket)
