Add dynamic unit test dataset

[jtec]

We need movement to unit-test the Doppler observation (by estimating antenna velocity) and carrier phase outputs (by estimating displacement between epochs with carrier phase time differences) of prx. Without antenna displacement, sign errors are not observable.

@plutonheaven What do you think of https://www.kaggle.com/datasets/google/android-smartphones-high-accuracy-datasets? Should we use a 5s-slice of that dataset?

[plutonheaven]

Yes.
We could also do a data collect to write PRX in GPS art ^_^

I obtained the following 5s extract by using the following command on the rinex file from GSDC2021 "\train\2020-05-14-US-MTV-1\Pixel4\supplemental\Pixel4_GnssLog.20o"
.\gfzrnx_2.1.0_win64.exe -finp .\Pixel4_GnssLog.20o -epo_beg 20200514_221432 --duration 5 -fout ::RX3::

I chose a start epoch where the speed of the vehicle was large, around 25 m/s

I then passed it through RNX2CRX and gunzipped it.

XXXX00XXX_R_20201352214_05S_01S_MO.crx.gz

I will try to process it with prx later (or you can if you have time).
