Dim down buttons not processed on 4-way and 8-way switches

[mtulen888]

Does the issue really belong here?

• I definitively want to report a bug within deCONZ or its REST-API

Is there already an existing issue for this?

• I have searched the existing issues and there is none for the bug at hand

Describe the bug

Dim down buttons (2, 4, 6, 8) not processed on 4-way and 8-way switches ROB_200-007-0 / ROB_200-008-0, SW build ID 2.7.6_r27

Logging says:
[INFO] - No button handler for: ROB_200-007-0, broadcast to: 0x2BC1, endpoint: 0x01, cluster: LEVEL_CONTROL (0x0008), command: MOVE (0x01), payload: 01320000, zclSeq: 101

Dim up buttons (1, 3, 5, 7) do work.

Logging:
[INFO] - Button 1001 - ROB_200-007-0, broadcast to: 0x6791, endpoint: 0x01, cluster: LEVEL_CONTROL (0x0008), action: Move up (with on/off), payload: 0032, zclSeq: 103

Steps to reproduce the behavior

"Add new switch", "Other" --> switch added succesfully.

Group, switch editor, Assign Dim up/on to button 1, assign Dim down/off to button 2.

Hold button 1 --> scene dims up
Hold button 2 --> nothing happens

Expected behavior

Hold button 2 --> scene dims down
