plugins: adrv9002: implemented profile generator tab

- similar UI to Transceiver Evaluation Software (TES)
- can save profile and stream image to files or write them to device
- 2 presets available for default profile values: live device (read from device) and LTE
- error messages are displayed in Debug info section (profile generation errors are also displayed)

- requires navassa-profile-gen-cli to work
- included cJSON for generating the adrv9002 structure config

CI/appveyor: Get the compiled dependencies from a Github release

The artifacts stored in the appveyor build expire after 6 months. Since
the iio-osc-mingw gets rarely modified we're better off downloading the
dependecies from the artifacs section of the latest iio-osc-mingw
release.

oscplot.c: Fix segfault when enabling markers in frequency domain

The issue was introduced when the deprecated gtk_signal_connect has been removed (commit 51ce390). It's equivalent is g_signal_connect_swapped and not g_signal_connect_object.

oscplot: fix memory corruption in plot_setup()

When initializing a FFT plot, plot_setup initializes the transform
as well as the X and Y axis and passes the handles to the gtkdatabox library.
After initialization osc_plot_update_rx_lbl is called which calls transform_setup,
invalidating the handles sent to the gtkdatabox. This causes gtkdatabox to apply
operations on invalid memory areas. To fix this, we make sure we don't reinitialize
the transform on initial setup.
