This version mainly addresses two issues:

The module cannot join the multicast group when using a switch with IGMP snooping / multicast management enabled.

On some models, there is a channel mapping error when using TDM8.

Newly provided feature:

Bit 15 of register 6 is defined as the switch bit between the master-backup function and the output delay function. When the default value is 0, the master-backup function is enabled. If set to 1, it switches to output delay.
