#7 -o flag not honored with -fa

[Private Citizen]

The -fa flag sends ascii to stdout, and ignores the existence of the -o flag. The following both print the ascii to the screen:

$ echo foo | dmtxwrite -fa
echo foo | dmtxwrite -fa -o bar

when a reasonable person might expect the output to be sent to the file named bar. However, shell redirection works as expected:

$ echo foo | dmtxwrite -fa > bar

The behavior of the -o flag should be consistent, regardless of the output format.

Good suggestion -- This issue arose from the same problem as bug 1866550, which is now closed. The root cause was that I didn't intend for -fa and -fc to be treated as valid "scannable" barcode output, and as such they print to STDOUT without paying attention to the -o switch.

Bug 1866550 was addressed by instead treating the ASCII-art (-fa) and codeword (-fc) output as "preview" options (-pa and -pc), which is now defined in the --help as something that prints to STDOUT. If a user still requires this to be captured in a file then they can use the same redirection or pipes as they would use with verbose log messages.

Thanks for the suggestion!
