Use chandra_time modules for Chandra.Time

[taldcroft]

Description

This is an idea to fix #57 in which the modules and classes from the chandra_time package are used for both chandra_time and Chandra.Time.

This is a little weird and I'm not sure if there is some gotcha with this solution, but it does seem to work.

    `numpy.distutils` is deprecated since NumPy 1.23.0, as a result
    of the deprecation of `distutils` itself. It will be removed for
    Python >= 3.12. For older Python versions it will remain present.
    It is recommended to use `setuptools < 60.0` for those Python versions.
