Add support for ilo5 versions

[naorc123]

Hey,
There is the file firmware.conf, we pull our ILO versions from it.
according to HP release there are newer versions.
Can you update the repository so maintain also newer ilo5 versions?

I'm just noticing this as well. Any updates?

From me as an outsider, it looks like PR are handled normally (ref: #228) so if you need this, maybe just do the work instead of waiting/pressuring others to do it for you?

Newer versions have been added to firmware.conf
