Iaga sampling rate

Fixed odds and ends,  and made convert_stream_to_masked, and _convert_trace_to_int non destrutive calls

Refactored to reflect the change to write out an entire channel before closing socket. Also divided out buffer creation, from sending buffer.

Added static variables of FORCEOUT and TAG to keep -1/-2 number of sample special cases from getting mixed up,  like I did.

Removed cwbhost/cwbport logic from code, will let EdgeFactory deal with that. Rewrote the get_tag routine to use strings, which only work if the string is spliced to exactly 12 characters.  Rewrote the get_tag routine to remove the sequence code.  Rewrote the sequence code for data packets to use class variables. Other cleanup, especially comments.

Refactored code to put one channel at a time,  instead of one trace at a time, to fix a problem with writing to edge. Added logic to use cwbhost/cwbport if data is older then 10 days, and the cwbhost/cwbport are provided. Added starttime/endtime to put_timeseries to match algorithm base class. Other cleanup as discovered.

Refactored to clean things up and improve readability,  added comments.  Committing now,  because it mainly works.

Completed comments.  Changed _send_trace to _put_trace, and moved RawInputClient initialization and close into _put_trace.  Added routines to change a trace to a masked array, and change channels into int.
