Parse integer as bitfield?

[llamafilm]

Ross OpenGear MIBs do several unusual things, one of which is encoding a status value as a bitfield in an integer type. Is there any way to parse this with snmp-exporter? Ideally, I think this ought to be 12 separate metrics, each with a value of 1 or 0 to indicate failures.

Example from MIB

openGearFrameStatus    OBJECT-TYPE
    SYNTAX      Integer32
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION
      "The overall hardware status of the frame.  Zero means all OK.
       Any nonzero value indicates an error condition.  The status value
       is a bitfield, where each bit represents a different error:
          0x0001 - the fan door has been open too long.
          0x0002 - psu fuse blown.
          0x0004 - psu fault.
          0x0008 - psu is overloaded
          0x0010 - psu fan has stalled
          0x0020 - a frame-door fan has stalled
          0x0040 - error condition(s) reported by card(s)
       The following additional bits apply to OG3-FR high power frame only:
          0x0080 - the reference card is missing/faulty
          0x0100 - psu AC missing
          0x0200 - psu power off
          0x0400 - psu is overloaded
          0x0800 - card warning
       "
    ::= { openGearFrameHardwareEntry 1 }

It looks like this in the exporter, with the value 0 meaning there are no errors:

openGearFrameStatus{openGearFrameIndex="1"} 0

Whoops, I should have searched first. Closing this because there's an open issue #1310.
