Example routines in bits.php for bit stream decoding
A lot of bugfixes and adaptions on the original JeeLabs OokRelay2

ookRelay2
-Trimmed OOK frequency 868.25 to 868.35 MHz
-Trimmed OOK 400kHz bandwidth
-Trimmed OOK GAIn -20db; DRSSI 97dbm

FSxDecoder class
- Added SYNC state, to let the 13 "Sync" pulse of the preamble not to
count as a pulse. This caused a wrong/shifted output in the original
version
- gotBit moved to this class, which overrides the common gotBit routine
- gotBit: Reversed the input of the bits, so first b7 instead of b0
- Added parity check

DecodeOOK class
- Added a resetDecoder after received a repeated message, otherwise
there will be always the last message in the buffer. This last message
was received directly before a new message was received, with delay.

KSxDecoder class
- Reset the next received byte, so no bits will be left
- bitCounter for msgType 1 (S300) and 7 (KS300), which results in a
fast end of message and response
- Added receive preambl logic and a SYNC state
- Checking last nible bit is '1'
