Added partial record data retrieval function in PakBus data collection. We now only respond with one table, even if the data collection asks for more than one table.
Added new MaxTXPacket setting that allows control over the maximum packet size transmitted by the datalogger.
Modified the datalogger's response to the SDI-12 aI! command to return the Campbell manufacture name, etc.
Changed SDI12Recorder() so that SDI-12 D commands can be sent; i.e., aD0! can be sent and behaves like the 0R0! Command.
Fixed a problem with back-to-back print instructions. The second print was aborting the transmission of the last character sent by the previous print.
