Formula empty string value handling #349

Closed jqnatividad closed 10 months ago

jqnatividad commented 10 months ago

alternative to @7Towers' PR (#348 ) but returning DataType::String("".to_string()) instead of just None to align calamine with how xlrd and sheetjs handles it per @dimastbk .

Also includes test, using test file provided by @dimastbk
