to-uint8 
Convert input array to uint8 array, detecting floats if required. Useful to ensure that an input array contains pixels/colors.
```js
var u8 = require('to-uint8')
var pixels = u8(0,0,0,1, 1,1,1,1) //
```
u8data = u8(data, detectFloat=true)
Return Uint8Array u8data with input data values, possibly converted from floats, if required. data can be an Array, Array of Arrays, TypedArray, Buffer, ArrayBuffer, base64 string or any other container.
```js
u8(new Uint16Array(0, 1, 2)) //
u8(new Float32Array(0, .5, 1)) //
u8(new Float64Array(0, .5, 1)) //
u8(0, .5, 1) //
u8(0,0,0,0, 1,1,1,1) //
// untyped array with int-ish values doesn't get converted
u8(0, 1, 255) //
// unless passed a flag to force conversion
u8(0, 1, 255, false) //
// bad data returns null
u8(/abc/) // null
```
