Can't load large image files

[lowlines]

The parser-async library doesn't check that the chunk size does not exceed the max buffer size and results in a RangeError [ERR_INVALID_OPT_VALUE]: The value "3221258240" is invalid for option "size" error when loading in very large image files. The image I was looking at was 32768x32768 and the goal was to slice it up into smaller 2000x2000 image tiles.

I have not dug too deeply into the source code, but I would imagine you'd need to manage an array of large buffer tiles in order to support loading very large images.
