TensorImage class
TensorImage is the wrapper class for Image object. When using image processing utils in
Flutter Helper library, it's common to convert image objects in variant types to TensorImage at
first.
IMPORTANT: Image always refers to Image from 'package:image/image.dart' and not those from
'dart:ui' or 'package:flutter/widgets.dart.
At present, only RGB images are supported, and the A channel is always ignored.
Details of data storage: a TensorImage object may have 2 potential sources of truth: a
Image or a TensorBuffer. TensorImage maintains the state and only
convert one to the other when needed.
IMPORTANT: The container doesn't own its data. Callers should not modify data objects those
are passed to BaseImageContainer.bufferImage or BaseImageContainer.tensorBuffer.
See ImageProcessor which is often used for transforming a TensorImage.
