add ILI9341 320x240 LCD driver

[mmoskal]

The ILI9341 driver should be the same as ST7735 except for the init sequence and screen size. An example init sequence is here
https://github.com/adafruit/Adafruit_ILI9341/blob/master/Adafruit_ILI9341.cpp#L151-L178

A new class needs to be added similar to this

devicescript/packages/drivers/src/st7735.ts

Lines 247 to 264 in 9cd49ae

	export interface ST7735Options extends STLikeDisplayOptions {}
	export class ST7735Driver extends STLikeDisplayDriver {
	constructor(image: Image, options: ST7735Options) {
	super(
	image,
	options,
	hex`
	01 80 78 // SWRESET + 120ms
	11 80 78 // SLPOUT + 120ms
	20 00 // INVOFF
	3A 01 05 // COLMOD 16bit
	13 80 0A // NORON + 10ms
	29 80 0A // DISPON + 10ms
	`
	)
	}
	}

The main thing is to test it with hardware

** Datasheet, firmware, etc... **

This works as a basic implementation:

export interface ILI934xOptions extends STLikeDisplayOptions { }

export class ILI934xDriver extends STLikeDisplayDriver {
    constructor(image: Image, options: ILI934xOptions) {
        super(
            image,
            options,
            hex`
01 80 80 // software reset
ED 04 64 03 12 81 //power on sequence control
3A 01 55 // pixel format
B1 02 00 18 // FRMCTR1
B6 03 08 A2 27 // display function control
11 80 78
29 80 78
`
        )
    }
}

Tested on an adafruit 320x240 ILI9340C
it'll probably be worth adding more options but i'm currently unsure what exactly would be useful (ie what varies between products)
