pytplot.get_ylimits return type is wrong

[xandrd]

According to the documentation pytplot.get_ylimits, presumably should return the numeric value. However it returns DataArray

Code to reproduce

import pytplot
x_data = [1, 2, 3, 4, 5]
y_data = [1, 2, 3, 4, 5]
pytplot.store_data("Variable1", data={'x': x_data, 'y': y_data})
y1, y2 = pytplot.get_ylimits("Variable1")
print(type(y1))

Output

<class 'xarray.core.dataarray.DataArray'>

Expected

<class 'int'>

[xandrd]

get_ylimits is updated to match the expected behavior.
