MSR206 raw write

[GoogleCodeExporter]

I have a problem writing raw data to my cards. I get wring data on the card. 
The written data it's not random, it's deterministic, so I thought about an 
encoding error or so.

I used a Windows program which came with the writer which allowed me to write 
the card successfully. So the problem had to be with the library. I sniffed the 
communications using wireshark-usb and I saw that the write command triggered 
by the Windows software was sending different data but in the end, after a 
write, I could read my data perfectly.

So the conclusion is: in order to write the cards correctly I have to send the 
data reversing the bits in each byte. I don't know if that's a problem, an 
issue or a feature, but the fact it's that libmsr won't write my cards.

I've patched it so the write operation takes care to reverse the bitorder.

Is anyone interested in my patch? I can upload it if you want.

Thank you for the source BTW!

I've got the same issue, although I've got an MSR605 (but it seems almost 
identical).
If you could attach a patch, that'd be awesome!

Cheers.

My pleasure!
Here it goes the diff. It would be nice that some mantainer commented on it.
