np.trapz is deprecated

numpy 2.0 deprecated np.trapz. A possible replacement function is np.trapezoid

Thanks for noting this @sbruto, and #45 is much appreciated.

As noted in the PR I'm a little worried that this breaks in numpy < 2.0 which is still not all that old and sometimes useful when installed alongside older codes. But I agree it would be good to prepare for a removal of trapz.

I see the point on maintaining support for numpy < 2.0 and I like your suggestion for the try/except import of trapz. I had been ignoring the trapz deprecation warning for a while and it finally broke, which prompted me going for a fix. I've found sedpy very useful, thank you for developing it.

I'm attempting the try/except fix real quick.
