viewer with CAN-FD, print packets with variable DLC but same ID in different lines

### Is your feature request related to a problem? Please describe.

I am reading the CAN-FD bus of BOSCH SMART SYSTEM ebikes. For example packets with ID 0x507 can have data lengths of 20, 24, 32 ,48. They are written on top of each other in the console output of the viewer script and count is reset.

### Describe the solution you'd like

Use a separate line for a packet with same ID and same DLC. Note that CAN FD there can be various DLCs for same IDs
