Is your feature request related to a problem? Please describe.
Default implementation of tuya mcu api in xdrv_16_tuyamcu.ino support only dimmer with one channel. Also we need two brightness sliders in web interface,

Describe the solution you'd like
Support for two brightness sliders in web interface when fnId: 22 (2nd dimmer) is define with non zero dpId. I tried to add TUYA_MCU_FUNC_DIMMER2 to xdrv_16_tuyamcu.ino but workaround with two sliders from PWM dimmer sends dim command to 2 channels. Also input from button send on/off state to 2 channels. Likely bad executecommand in:
if (fnId == TUYA_MCU_FUNC_DIMMER2) { //2 channel AddLog_P2(LOG_LEVEL_DEBUG, PSTR("TYA: 2CH RX Dim State=%d"), packetValue); Tuya.new_dim2 = changeUIntScale(packetValue, 0, Settings.dimmer_hw_max, 0, 100); if (Tuya.ignore_dimmer_cmd_timeout2 < millis()) { if ((power || Settings.flag3.tuya_apply_o20) && // SetOption54 - Apply SetOption20 settings to Tuya device (Tuya.new_dim2 > 0) && (abs(Tuya.new_dim2 - Settings.light_dimmer) > 1)) { Tuya.ignore_dim2 = true; snprintf_P(scmnd, sizeof(scmnd), PSTR(D_CMND_DIMMER "3 %d"), Tuya.new_dim2 ); ExecuteCommand(scmnd, SRC_SWITCH); } }

Describe alternatives you've considered
