Changelog

v0.3.9

Added a delta marker
Segments can now have exponential different step widths (see logarithmic sweeping)
More different data points selectable (shorter are useful on logarithmic sweeping)
Scrollable marker column
Markers initialize on start, middle, end
Frequency input is now more "lazy" 10m, 50K and 1g are now valid for 10MHz, 50kHz and 1GHz
Added a wavelength field to Markers
32 bit windows binaries build in actions
Stability improvements due to better exception handling
Workaround for wrong first S21mag value on V2 devices

Sweep worker now initializes full dataset on setting changes. Therefore no resize of charts when doing multi segment sweep
Changing datapoints in DeviceSettings are reflected in SweepSettings widget step size
Simplified calibration code by just using scipy.interp1d with fill_value
Established Interface class to ease locking and allow non usb connections in future
Cleaned up VNA code. Added some pause statements to get more robust readings
Added MagLoopAnalysis
Touchstone class can now generate interpolated Datapoints for a given frequency Will be usefull in future analysis code
Fixed a bug in Version comparison

Fixed data acquisition with S-A-A-2 / NanoVNA V2
Refactored calibration code
Calibration data between known datapoints in now interpolated by spline interpolation
Fixed through calibration

fixed crash with averaging sweeps also averaging now discards reading by geometrical distance
