Obtain spectral lines from NED query

Hello,

it seems that it is not possible to obtain the spectral lines from a NED query.

(I am referring to these in the NED search, for clarity)

It seems that the `photometry` table is available via the `get_table` method, but this - as the name suggests - incudes only photometric measurements.
On the other hand, one can fetch the spectra with `get_spectra`.
But I'd like to access directly the line information.
Any workaround?

Best, and thank you!

Start by reviewing the NED query entry points mentioned in the issue, especially get_table and get_spectra, and determine whether NED exposes spectral-line data through a separate response or table. Done should provide a documented way to access the requested line information directly, with coverage for the resulting behavior in the relevant tests.
