More and more Tuya MCU based devices are coming in the market and people requesting to support them. This patch makes Tuya module more configurable and easier to add new functionalities. Its not just a dimmer or a switch anymore.
After this Patch Tuya MCU module has a list of supported functions and the user would need to map the functionId to dpId of their device. Once mapped correctly the Tuya module will take care for handling proper function for dpId.
Currently functions supported are
1. Relays1 to 8 : FunctionID 11 to 18
2. Dimmer : FunctionID 21
3. Power ( Deca Watt ) : Function ID 31
4. Current ( milli Amps ) : Function ID 32
5. Voltage ( deca Volts ) : Function ID 33
The changes are
- Use a TuyaMCU command to map DPs to Functions instead of many different SetOptions. SetOption41, 44, 45, 46, 65 won't be needed after this patch.
- TuyaMCU command takes argument like `11,1` which means Map Function id 11 (Relay1) to DPID 1
- Migrates old settings flags and options to new TuyaMap command
Capable Tuya serial devices send power metering data over serial interface. User needs to identify the ids of all power metering functions and set as
SetOption44 -> Voltage
SetOption45 -> Current
SetOption46 -> Power
New Tuya Dimmer has dim values from 0 to 24. Currently the code expects it to be 0-100 or 0-255.
With this change we move the flag to a param and use that to calculate correct dim percentage.
This change also makes sure to update settings on version upgrade.
Tuya serial dimmer doesn't switch on from HASS because when powered off, HASS sends dimmer command.
Internally, dimmer update and power command are sent too quickly to serial out and switch doesn't turn on.
Adding a delay fixes things.
Tuya switches are detected as dimmers even after setting SetOption65 to 1.
Currently SetOption65 just hides the dimmer from Web UI for Tuya switches with SetOption65 to 1 but they are advertised as dimmer to HASS.
With this change we set light_type to LT_BASIC (on/off) instead of LT_SERIAL1 (dimmable) when option 65 is set.
This tuya dimmer mcu sends data for multiple dimmer ids which breaks `tuya_ignore_dim` logic and sometimes when `power on` is sent its blocked due to multiple serial commands being sent at the same time. This patch makes sure we send dimmer commands only when we need to.

Change Summary
1. Added Option to select Dimmer Range (1-100 and 1-255) through SetOption66 (default is 1-100 for legacy device support
2. Updated Dimmer code to set range based on the option66 100 / 225
* Updated xdrv_01_webserver.ino to show dimmer slider2 by default for Tuya Dimmer Module
* Updated xdrv_16_tuyadimmer.ino remove the use of XdrvMailbox and removed the pow functions now the size for 6.5.0 build is 510kb
* updated sonoff.ino to hold current device id
Some newer dimmer modules require the stock firmware method of sending a heartbeat packet every 10-11 seconds to the secondary MCU. This was tested on 2 other Tuya based dimmers that did not require this heartbeat packet and no adverse impacts have been found.
