The order of the pivot table supports custom fields

[liuwangchao]

Description

Steps to reproduce the issue:

1. I created a pivot table by this simple data and generated a simple pivot table
   
   

2. But after I use Excel's Analyze - Fields, Items, and Sets - Calculated Fields function to add a field, and call func (f *File) getPivotTable(sheet, pivotTableXML, pivotCacheRels string)
   
   
   

Describe the results you received:

I get panic: "msg":"runtime error: index out of range [3] with length 3"

Describe the results you expected:

The error was reported at line 955 of the func (f *File) extractPivotTableFields(order []string, pt *xlsxPivotTableDefinition, opts *PivotTableOptions), the pivot table has four fields, but the length of the ORDER is still 3.

Output of go version:
