[Observium] Show ink levels for Ricoh printers

Hi All

This is a message to ask people can they try these SNMP OIDs in the link below on there Ricoh printers?

We have a few Ricoh printers that just show SOME SPACE in observium and would love to see values!

I discovered this link by accident and they appear to be working on our few printers!

Currently using the printer-mib only reveilles -3, -2, -1 which isnt helpful...

But the link below uses ricohs private mib which appears to work!

If they work for others, could the wonderful amazing observium team implement these oids into the existing checker to show stats :)
