No support for decanes

[milanpredic]

Here are some helpful functions to calculate decanes based on Chaldean order. Maybe you could merge it into code.

Cheers

from flatlib import const

# Decane rulers based on the Chaldean order
DECANE_RULERS = [
    # Aries
    const.MARS, const.SUN, const.VENUS,
    # Taurus
    const.VENUS, const.MERCURY, const.MOON,
    # Gemini

Hi @milanpredic, I have lots of functions and tables regarding essential dignities (decane rules included) at https://github.com/flatangle/flatlib/tree/master/flatlib/dignities. You can find everything in those files..
