more than 1 call to JsBarcode errors api.options(...)[options.format] is not a function

Nobody has claimed this yet.

```
var upc=new Image()
new JsBarcode(
upc,
"796030114977",
{
format: "UPC",
width: 3,
height: 80,
}
)
var cno=new Image()
new JsBarcode(
cno,
"796030114977",
{
format: "UPC",
width: 3,
height: 80,
}
)
```

on the second call i get
```
runtime-core.esm-bundler.js?5c40:218 Uncaught TypeError: api.options(...)[options.format] is not a function
at JsBarcode (JsBarcode.js?62c5:76)
...
```

Start at JsBarcode.js around line 76 and reproduce the two consecutive JsBarcode calls shown in the issue. Trace why the second call reaches the reported options.format error, then verify that the same two-call example completes without the exception.
