Request for extended I2C LCD & OLED support.

[costo]

It is very nice that we can use displays in ESPEasy, but there are a few limitations that can be hard to overcome.
For instance the ESPEasy software assumes that all LCD displays have I2C address 0x27 and that all OLED displays have I2C address 0x3C.

OLED's are often switchable between address 0x3C and 0x3D with some sort of jumper.
Usually 20x4 and 16x2 LCD's have an I2C interface board that can be set with (solder)jumpers between 0x20 and 0x27. (ocasionally between 0x38 and 0x3F depending on the type, a PCF8574 or a PCF8574A)

So my wish is to see in the device tab under 'Optional Settings' a choice to fill in the actual I2C address or choose the I2C address. that the scanner has found.
For OLED 3C or 3D and for LCD between 20/27, than it is very easy to use different displays without the need to go into the device plugins and change the address in the source code recompile the code and flash the ESP.

Also a wish of me is to have OLED SSD1306 support for screen rotation. This could also be implemented as a choice between 2 options, 'normal' and 'rotated' in the Optional Settings tab of the OLED device.

I know that both extensions are not so difficult to implement, but I guess Martinus has to fix it so that every ESPEasy user can benefit from it.

I'll try to implement this with the next development build.

R54 is available and has the proposed features. Also included are the following commands:
OLEDCMD,On
OLEDCMD,Off
LCDCMD,On
LCDCMD,Off

For the LCD display, it will turn the backlight on or off.

Perfect execution. Thank you, going to test it.

Having tested the new plugin I found a little bug in the LCD part .

I choose a 4x20 LCD and have 4 lines,
line 1 '11111111111111111111' 20x'1'
line 2 '22222222222222222222' 20x'2'
line 3 '33333333333333333333' 20x'3'
line 4 '44444444444444444444' 20x'4'.

The LCD display is stubborn and displays like this:

Confirmed bug. Will be fixed in R55.
