PTU not printed in JSON in silent mode

[danijelt]

I noticed that decoder demod/mod/rs41mod.c doesn't print PTU in JSON in silent mode, because both getting the PTU data and printing it in non-JSON mode is handled in the same if block.

It can be easily fixed with this patch:

diff --git a/demod/mod/rs41mod.c b/demod/mod/rs41mod.c

-                if (gpx->option.ptu && out && !sat && !encrypted && pck_ptu > 0) {

                     err0 = get_PTU(gpx, ofs_ptu, pck_ptu, !err3);

+                    if (!err0 && out) prn_ptu(gpx);
                 }
                 pck_ptu = 0;

I can't test other decoders at the moment to see if they are affected too, and due to different code in each decoder I can't simply grep for the relevant section. Otherwise, I'd submit a pull request.

Fixed, thank you.
