New DataClass.hstack

[mkelley]

DataClass.hstack will append another object's columns:

import astropy.units as u
from sbpy.data import DataClass

data1 = DataClass.from_dict({"rh": [1, 2, 3] * u.au, "delta": [1, 2, 3] * u.au})
data2 = DataClass.from_dict({"phase": [60, 30, 15] * u.deg})
data1.hstack(data2)

It uses astropy's hstack and will rename columns as needed to avoid DataClass field name collisions.
