add ability to choose ws

Hi,
I added the ability to choose specific worksheet.
That can be handy when you have more than one worksheet, the default is steel the first worksheet.

    const fileHandler = (event) => {
        let fileObj = event.target.files[0];
    
        //just pass the fileObj as parameter
        ExcelRenderer(fileObj, (err, resp) => {
            if(err){
                console.log(err);            
            }
            else{
                debugger;
                console.log(resp)
            }
        }, 4);               
    }

    const fileHandler = (event) => {
        let fileObj = event.target.files[0];
    
        //just pass the fileObj as parameter
        ExcelRenderer(fileObj, (err, resp) => {
            if(err){
                console.log(err);            
            }
            else{
                debugger;
                console.log(resp)
            }
        }, "worksheet-name");               
    }
