Romain Porte 737cc3176e First implementation of software barcode
Actually the hardware barcode implementation is very specific and not
generic enough for just adding a `soft_render=True` argument to it. This
is a first work that can be improved with other commits, maybe for
merging this method in the `barcode` method after some cleanup.

The width, height and text_distance were set using empiric
print-and-retry tests so that the generated barcode looks nice to the
eye (and to the eye of an Android scanner tool.

!WARNING! Printing a barcode that is too large in width will result in
the printer to go crazy trying to print an image that is too large for
it. This may be fixed by raising an exception in the `image` method.

use jaconv instead of jcconv for japanese chars
jaconv is available for more Python-versions and seems to be more
professional. Apart from that I added jaconv to the test-requirements
but not the requirements. (If the katakana-stuff really works we can
later add it as a real dependency)

refactor access of private member _img of qrcode
Since version 2.5 python-qrcode allows the direct access of the
PIL-functions. (We require version 4 and above).
Thus, we can simply call qr_img.convert() without accessing the private
member.
This refactoring is identical in functionality.

Patrick Kanzler 0cfedb5706 add automatic codepage-changing
This code is adapted from the works by Frédéric Van der Essen in
pyxmlescpos.
I had to adapt the code completely in order to make it compatible with
modern unicode-handling

Further changes:
* improve text unittests in CLI and MagicEncode with hypothesis
* add feature force_encoding in order to enable old behaviour
* disable cli_text_test (for now)
* fix charcode(): it does now cooperate with the new structure
* remove redundant variable codepage from class Escpos

Patrick Kanzler 3d98eb8b9c fix file-printer did not flush
The file-printer did not automatically flush and thus behaved
differently to the other printer-classes.
Now the default behaviour is to flush after every call of _raw(). This
can be disabled by calling the file-printer with auto_flush=False.

Patrick Kanzler 9f5eed0020
add version-strings into the module
The version string is in the module as __version__ available.
In the doc the version will be automatically parsed. The version comes
from the installed module if on read the docs or directly from
setuptools_scm if you are working locally.
The CLI will issue the version string if you call it with the option
'version'. The CLI does not accept commands like '--version', since this
would not be conform with the rest of the interface (and argparse).

The configuration for loading the version-string is adapted from
pimutils/vdirsyncer. It autogenerates a version string setuptools_scm at
install-time and then adds it to the __version__ member in __init__.py

I adapted the GitHub-template with a fitting comment and bumped the
changelog.
