Expected behavior

The code should compile successfully when MB_FUNC_OTHER_REP_SLAVEID_ENABLED or MB_FUNC_OTHER_REP_SLAVEID_BUF are disabled.

In main brachen, the 8215e3d commit has compilation problems due to the following line:
https://github.com/espressif/esp-modbus/blame/eeeab170be289376b7a9915a82ef874c52d86acf/modbus/mb_controller/serial/mbc_serial_master.c#L264

Actual behavior (suspected bug)

When building the project with MB_FUNC_OTHER_REP_SLAVEID_ENABLED or MB_FUNC_OTHER_REP_SLAVEID_BUF undefined, compilation fails due to an unguarded call to mbm_rq_custom() in mbc_serial_master.c. The function is implicitly declared, leading to a compiler error.

This seems to be declared only for these macros in file main/modbus/mb_objects/functions/mbfuncother.c.

Error logs or terminal output

<project_root>/EasyHomeControl-ESP32/managed_components/espressif__esp-modbus/modbus/mb_controller/serial/mbc_serial_master.c: In function 'mbc_serial_master_send_request':
<project_root>/HomeControl/EasyHomeControl-ESP32/managed_components/espressif__esp-modbus/modbus/mb_controller/serial/mbc_serial_master.c:264:28: error: implicit declaration of function 'mbm_rq_custom' [-Wimplicit-function-declaration]
  264 |                 mb_error = mbm_rq_custom(mbm_controller_iface->mb_base, mb_slave_addr, mb_command,
      |

Steps to reproduce the behavior

1. Disable CONFIG_FMB_CONTROLLER_SLAVE_ID_SUPPORT=n in sdkconfig.
2. Build the Modbus master example located at examples/serial/mb_serial_master.
3. Crash in the logs.
