Take more than 10 second to read an epub that 8MB

[armanhadifatah]

I have a larg epub which contain images and near 1000 pages

it takes 10 second to read , i think it should read couple of page at a time not to read the whole book.

@armanhadifatah
I had the same problem, made a trick to load much faster, 10 seconds may reduce to 0.5 to 1.0 seconds.
I modified dart-epub to read chapters on demand.

@controladad Hi Adad, could you make a PR for the changes? If it could benefit us, maybe we can get it merged?
