401 sweep points

[galileo-pkm]

Small change to enable 401 points on H4.

This fix does not work for me. I am using a SOLT 401pt calibration stored on my NanoVNA-H4 1MHZ to 1.5GHz. Whenever I add the 401 option and try to execute I get the following error:
2021-02-06 23:48:40,439 - NanoVNASaver.SweepWorker - ERROR - list index out of range
Traceback (most recent call last):

IndexError: list index out of range

The other datapoint selection options work correctly including the 201 datapoint selection. Im a Fortran programmer unfamiliar with python so fixing this myself will require a steep learning curve. The only other bug I noticed is that the bandwidth is doubled on my NanonVNA from what is selected in nanovna-saver. Im using firmware 1.0.45 from DiSLord. OS: WIndows 10 running Python 3.9.

I can't trigger that behaviour locally but even if I could it would not mean much because I'm not
a Python developer.
FWIW I have been using this on top of pull #368 and haven't seen any issues.
