The NF calculated by the preamp model is compliant with the MW-MW noise
mask in the OpenROADM MSA spec. The booster is noise-free, which is
modeled by setting the NF to zero (-inf in dB units). This is obviously
unphysical but it is the simplest way to model the total noise
contribution from a ROADM, including preamp and booster, that is
compliant with the the OpenROADM MSA.
This also introduces two new EDFA type varieties,
"openroadm_mw_mw_preamp" and "openroadm_mw_mw_booster" in the equipment
library. I would prefer to also change the names of the existing
"openroadm" type_def and "standard"/"low_noise" type_variety,
representing an OpenROADM inline-amplifier, for better consistency but
this probably needs to be discussed first.

In the generated SVG files, there was a '%3' shown as a mouseover
tooltip on mouse hover. Apparently that's what ended up in the <title>
of the whole generated SVG document.
This turned out to be an internal thingy in graphviz/dot. In Sphinx
there's already some support for catching element IDs with this '%3'
madness, but apparently titles are not handled like that.
Solve this simply by providing a title for the whole `graph {}` stanza
in the embedded dot graphs.
