feat(widgets/circular_progress_bar): SpiralProgressBar added with rpc interface

Description

New spiral progress bar for nested scans available for rpc interface.

Full documentations coming with #190 (closed) and #189 (closed).

In rpc interface can be added like this after launching BECIPythonClient:

d2 = gui.add_dock()
bar = d2.add_widget_bec("SpiralProgressBar")

# example of usage
bar.set_number_of_bars(5) 
bar.set_colors_from_map('viridis')
bar.set_value([10,20,30,40,50])

this behaviour can be scriptable with for example scan status endpoint for scan progress.

By default the progress bar is set to be updated from scan_segment endpoint automatically configuring itself for 'scan_motors'.

Auto updates can be disabled by bar.enable_scan_updates(False).

In next step I would like to include some text information in the middle of the widget such as what is actually on which circle or some scan info/metadata.
