* bug/doc: Fix invalid EAN-13 barcode in examples
In the various examples and python-escpos CLI there are a number of uses
of `13243546557687` as an EAN-13 example. This EAN barcode is invalid
as the checksum should be `0` and not `7`.
```
$ python test_print.py
Traceback (most recent call last):
File "test_print.py", line 5, in <module>
p.barcode('13243546557687', 'EAN13', 64, 2, '', '')
File "/home/pi/fatt-display/lib/python3.7/site-packages/escpos/escpos.py", line 433, in barcode
bc=bc,
escpos.exceptions.BarcodeCodeError: No Barcode code was supplied (Barcode '13243546557687' not in a valid format for type 'EAN13')
```
This patch set removes `13243546557687` and replaces it with the valid
number `40063813339310`.
In researching the list of [assigned prefixes issued by
G1][g1-prefixes] there seemed to be no "officially" defined test prefix, so
this change was made to be minimally invasive using the number from the
existing test cases.
Resolves#350
Affects #176

Rendering to /dev/null by a call to .write causes an error. Calling .render directly is simpler and fixes the error.
