UPC/UPCA final output doesn't include guard bars

[logikonabstractions]

I'm being told (not a barcode format specialist) that the standard presentation for a UPC/UPCA code should look like this:

If I generate this barcode using the following code however, I get this:

Issues:

Added "F" at the end?

Any way to turn this off?

Guardbars not displayed

As I seem to understand, the standard/typical presentation for those code should include guardbars. I tried adding the "guardbars" keywords but it seems the UPC class doesn't accept that argument.

Code:

python-barcode create 686254053919 upc

Also generated as part of a server-side rendering, with same result:

UPCA(str(value["code"]), writer=SVGWriter(), guardbars=True).write(file)

Indeed, it's not implemented for that class. Patches welcome.

Added "F" at the end?

This still scans correctly right, it merely should be excluded from the text, right?
