Fix missing data matrix quality parameter

[mikelei8291]

The quality parameter of the data matrix command was missing. This commit fix the issue.

As you can see in the code comment above, there is the mandatory quality parameter set to 200, which is the only valid value now.

Labelary documentation of the quality parameter:

quality: The level of error correction to apply. Valid values are 0 (ECC 0), 50 (ECC 50), 80 (ECC 80), 100 (ECC 100), 140 (ECC 140) and 200 (ECC 200). The default value is 0 (scan errors are detected but not corrected). Always use quality level 200 (ECC 200).

However, note that the documentation says "always use quality level 200", so I don't think it's necessary to implement all quality level settings.
