Jarno Rankinen f4eb787a10 gh-5 Fetch register data from bus 
- goburrow/modbus' ReadHoldingRegisters can only fetch 125 registers at a
time, so updateRegisters does several readings
- modbus.ReadHoldingRegisters returns a []byte, where each even byte represents
  the MSB of a int16/uint16 and every odd byte is the LSB
- updateRegisters loops through each response slice forming the 16-bit
  integers

Still need to figure out a way to properly handle the signed/unsigned
values, and also the enumerations and bitfields. Perhaps changing the
'signed' boolean to a byte and making that a bitfield representing the
value type would be a good way to go. The value can then be properly
formed when fetching it from the in-memory pingvinKL struct, while being
stored as an int(64) internally.
