add temparature below 18 in climate_ir_lg compononet

**Describe the problem you have/What new integration you would like**

i am not able to completely control my LG's IR AC with esphome through esp32.
i was only able to control my ac from 18°c -30°c temperature
it would be great if you add 16°c - 30°c in LG remote tranmitter i was able to receive IR signals from IR recevier and it is aoutomatically updating in HA Climate card.
but when i set it to less than 18°c (17,16) the ac will not respond to that signal
i think the problem is with lg_ir_climate integration or ir transmitter it only supports temperature ranges from 18°c -30°c

**Please describe your use case for this integration and alternatives you've tried:**

i trided it with arduino IDE using another board with IR_dumb v3 example and another board and ir trasmitter with esphomeand when i change the temperature in HA UI it is receving only downto 18°c after that when i set temperature to 17°c or 16°c it is dumping temperature as 18°c

using HA ui climate card

but when i do it with genuine ac remote comes with ac i get

**Additional context**

i am using latest versions of HA and ESPHOME
board: esp32-node mcu 32s
compononts: climate, remote_receiver, remote_transmitter
protocol: climate_ir_lg

Start by reproducing the issue through the climate_ir_lg integration with the reported ESP32 setup, Home Assistant climate card, and LG2 codes. Compare the transmitted output for 18°C with the genuine remote's 17°C and 16°C signals; done means temperatures below 18°C are transmitted distinctly and the air conditioner responds.
