The "sdo" example just lists SDOs (and doesn't work for all devices). Complimentary to #57 and to the docs from #54 but neither are required to merge.

This example reads an SDO with a known Index/Subindex using sdo_upload().

Example output:

$ RUST_LOG=debug cargo run --example read_sdo
[2025-11-02T06:46:33Z INFO  sdo] Opening EtherCAT master...
[2025-11-02T06:46:33Z DEBUG ethercat::master] Open EtherCAT Master /dev/EtherCAT0
[2025-11-02T06:46:33Z INFO  sdo] Reading SDO 0x6061/0 as int8...
SDO 0x6061/1 read int8 = 1

Verified using actual hardware (AS715N servo drive).
