calculate_dV in SotoStarShade : Conflicts in input , docstring and usage in minimize SlewTimes

[doctordoom54]

• calculate_dV method is called with less number of inputs in minimize_slewTimes. (for ex angular sep is not given as input)
• The order of inputs also appears to be flipped in respect to the definition of the method
• The inputs in calculate_dV don't match with the docstring
• Internally in minimize_slewTimes the slewTime is given as output without proper units (d) which causes error in calculate_dV
• calculate_dV fails to take in a single pair of targets (2 stars) and corresponding single slewTime.

Most of these errors can be checked visually, using SotoStarshade observatory module in a simulation should provide the same error.

Expected behavior Minimizing slewTime based on constraint equations.

EXOSIMS version:

• Current master branch ( v 3.13) contains the module with this error.
