Gnssrefl

added polyV to gnssir_input (polynomial used in direct signal removal)

added kadaster archive for 1-hz RINEX, Dutch site (kadaster.nl)

I somehow managed to delete the samplerate input to rinex2snr. My Apologies.
It is back in now.

The parallel processing code (management of the spawned processes) was
causing the code to crash when calling
rinex2snr or gnssir within a python function. I don't know enough to fix it -
but I did segregate it so that people that don't want parallel processing
can still directly access the code within rinex2snr_cl and gnssir_cl.
I did not fix nmea2snr_cl, so I think that has to be fixed if people want
to run nmea2snr_cl within a python function.

I fixed a bug in rinex2snr inputs read from the json. It was ignoring
command line requests (such as samplerate, orb, archive).

added archive and orb to the gnssir_input json. These are to be used in rinex2snr - mostly
useful for people (like me) that forget what command line options I want to use.
Other things you can save are mostly for RINEX 3 (e.g. stream parameter, samplerate). snr and dec values can also be
set if you are doing something non-standard (i.e. not using snr file 66 and not decimating).

Default for rinex3 files is now explicitly set to cddis. This is different than for RINEX 2.11 files where
the default is all, which now cycles thru unavco and sopac. It used to use sonel, but I don't think
many people use sonel. And if they want to use sonel, of course they can do so by specifying sonel.

Trying to make a log file for rinex2snr so that you are not overwhelmed with messages
to the screen. rinex3_rinex2 had to be changed to allow log input. and file needed to be
created in run_rinex2snr.

I added a debug option to rinex2snr so you could see what is going wrong without using
the task queues.

Making new pypi version with python 3.9 just to be sure we are all on the same page.
