Description

Story: BI-1199 - Choose file format for germplasm export

Refactoring file export logic to enable exporting to xls and csv formats
Modified ExcelWriter.java to write to xls as well as xlsx format
Added CSVWriter.java that takes in same data and columns as ExcelWriter but writes to a csv format
Added FileType enum to encompass information needed to write to each file type
Modified GermplasmController.java to take in file type and pass that on to BrAPIGermplasmService.java, which in turns calls the respective writer associated with the FileType
