Set error level and version about segno

[heuer]

You can specify the error level via parameter error and the version via parameter version. By default, segno tries to improve the error level. If you need a specific error level you can disable it via boost_error=False.

Example:

>>> import segno
>>> qr = segno.make('This is a test', error='m', version=15)
>>> qr.version
15
>>> qr.error
'H'
>>> # Segno changed the error level from M to H since there is enough space to improve the error level
>>> # Disable error boosting
>>> qr = segno.make('This is a test', error='m', version=15, boost_error=False)
>>> qr.version
15
>>> qr.error
'M'

PS:
If boost_error is enabled (default), Segno tries to improve the error level while keeping the specified version. Segno never changes the version to get a better error correction level.

If neither the version nor error correction level is specified, Segno creates a QR code with a minimal version (which fits for the given content), but maximal possible error correction level.
