Implement stock price foundation class

[MBizm]

This class shall provide the basis for a scene in which a share price is correlated to its leading index and indicate positive or negative trends via a clear speaking color coding which allows a human viewer to interpret whether urgent action may be required. the length of the led strip represents the trend over the period of time of a day, gradually filling up during the day (of the corresponding stock exchange). The color space may be restricted to indicate the most important trends due to led color capabilities.
The Neopixel Multibase class (https://github.com/MBizm/Catatumbo/blob/master/src/adafruit/core/neopixel_multibase.py) shall act as the basis as it will provide fundamental functionality, like reading configuration file, identify current location, state transition for scene switch. The implementation of the Neopixel Forecast class (https://github.com/MBizm/Catatumbo/blob/master/src/adafruit/controller/forecast/adafruit_forecast.py) can serve as a reference.
