Feature / add conjunction type to jupiter moons class

[Cannikev]

test_jupiterMoons.py

• add occultation Type to test_is_phenomena(self)
• test if occultation type is present during occultation(True/ False)
• Refactored test_is_phenomena(self) to remove TOL (not required)
• Refactored test_is_phenomena(self) to include Callisto

JupiterMoons.py

• add Conjunction Type to is_phenomena(epoch)
• Update examples

Probably should have verified before I made the PR - There was a couple of ways that I could have approached this, shout if you prefer the second option.

Current Implementation:
Example:

result_matrix=
[False, True, [None, True]]
[False, False, [None, None]]
[False, False, [None, None]]
[False, False, [None, None]]

Where:

    # Structure of result matrix
    # Row 0: Io            Column 0: Earth Occultation
    # Row 1: Europa        Column 1: Sun Occultation
    # Row 2: Ganymede      Column 2: Occultation Type  [Earth-Superior Conjunction, Sun-Superior Conjunction]
    # Row 3: Callisto      

    # Occultation Type (Superior Conjunction)
    # Column 1: Earth-Superior Conjunction (True: Jupiter occults moon, False: moon transits jupiter)
    # Column 2: Sun-Superior Conjunction (True: moon enters eclipse, False: shadow transits jupiter)

Option 2: This may be a bit neater, but it will break any existing implementation that may already be in use.
Example:

result_matrix =
[0, 1, None]
[0, 0, None]
[0, 0, None]
[0, 0, None]

Where:

    # Structure of result matrix
    # Row 0: Io            Column 0: 0=No occultation, 1=Moon in occultation, 2=Moon in transit
    # Row 1: Europa        Column 1: 0=No eclipse, 1=Moon in eclipse, 2=Moon shadow in transit
    # Row 2: Ganymede      Column 2: Not used
    # Row 3: Callisto
