To give a new option to export GSTR-1 in latest format Version V2.1.

The sample file for GSTR-1 V2.1 is kept here named as : GSTR1_Excel_Workbook_Template_V2.1.xlsx

There are basically major one change.
Earlier in GSTR-1 format there was only one workesheet for HSN Summary named as : hsn.
Here in this new V2.1 format there are basically separate HSN Summary for B2B and B2CS named as : hsn(b2b) and hsn(b2c).

There is also one folder kept in this folder as : Section_wise_CSV_files.
This folder contains the .csv files for GSTR-1.
Again the changes are same hsn(b2b) and hsn(b2c).
