ADD: well, starting with a luascript for reading calypso tags, made me remake the 14b raw command on client and device side. Sorry @marshmellow42 , but this one broke your "hf 14b info" implementation. I fixed the "hf 14b read" and the hf search. So not to bad, but still a bit broken. The 14b raw device side is now very similar to 14a raw. Which is good. There is a Standard 14b 0x050008 detection and STmicroelectronic 0x0600 detection on deviceside. This removes a lot of code client side.
I also made the SRi read functions better by combining them. The demodulation / uart code should be the same as last summers changes. The device side code can now be even smaller.
