NDCubeSequence.cube_like_dimensions Bug

[PCJY]

Describe the bug

When I call NDCubeSequence.cube_like_dimensions, it raises an error. With the following traceback:

Traceback (most recent call last):
  File "C:\Users\junya\ndcube-sandbox\SliceSequence.py", line 66, in <module>
    print('hereeeeeee',my_sequence.cube_like_dimensions)
  File "C:\Users\junya\ndcube-git\ndcube\ndcube_sequence.py", line 87, in cube_like_dimensions
    dimensions = list(self._dimensions)
AttributeError: 'NDCubeSequence' object has no attribute '_dimensions'. Did you mean: 'dimensions'?

To Reproduce

import astropy.units as u

import astropy.wcs

import numpy as np

from ndcube import NDCube, NDCubeSequence

# Define data arrays.

shape = (4, 4, 5)

data0 = np.random.rand(*shape)

data1 = np.random.rand(*shape)

data2 = np.random.rand(*shape)

data3 = np.random.rand(*shape)

# Define WCS transformations. Let all cubes have same WCS.

wcs = astropy.wcs.WCS(naxis=3)

wcs.wcs.ctype = 'WAVE', 'HPLT-TAN', 'HPLN-TAN'

wcs.wcs.cunit = 'Angstrom', 'deg', 'deg'

wcs.wcs.cdelt = 0.2, 0.5, 0.4

wcs.wcs.crpix = 0, 2, 2

wcs.wcs.crval = 10, 0.5, 1

# Instantiate NDCubes.

cube0 = NDCube(data0, wcs=wcs)

cube1 = NDCube(data1, wcs=wcs)

cube2 = NDCube(data2, wcs=wcs)

cube3 = NDCube(data3, wcs=wcs)

# Instantiate NDCubeSequence. Let the common axis be 0.

my_sequence = NDCubeSequence([cube0, cube1, cube2, cube3], common_axis=0)

print(my_sequence.cube_like_dimensions)
