minor docs update

[oskooi]

Closes #1314.

Did this, in fact, enable user-defined n and k values to be input into the absorption?

I am still running into issues, where meep-materials operate as expected, however, user-defined optical constants (at a single wavelength) yield a completely different result.

Thanks,
Beth

This PR was just a docs update to explicitly point out in Tutorial/Basics/Absorbed Power Density Map of a Lossy Cylinder that "This approach only works when the complex permittivity is specified using the Drude-Lorentzian susceptibility. Conductivity is not supported."

Following the discussion in #1314, you will need to fit your material data to a sum of Drude-Lorentzian terms as described in FAQ/How do I import n and k values into Meep?

Thanks for clarifying. Best, Beth
