RangeError: offset is out of bounds with with Tomosynthesis

[jeepMan79]

Hi Chris,

I'm testing out HTJ2K with your library and I'm getting the following error when trying to encode a Tomo image.

exception RangeError: offset is out of bounds
at Uint8Array.set ()
at encodePixelData (C:\work\code\sandbox\pocs\DICOMHTJ2K\encodePixelData.js:36:16)
at openjphjs.onRuntimeInitialized (C:\work\code\sandbox\pocs\DICOMHTJ2K\index.js:61:28)

It looks like the WASM code when getting the decoded buffer is calculating it smaller than expected.

I added some debug statements and here is the output from encodePixelData.js

Image Frame Data
{
width: 1990,
height: 3380,
bitsPerSample: 16,
componentCount: 1,
isSigned: false,
isUsingColorTransform: false
}

It seems like the WASM code is rounding down when calculating the bytesPerPixel in "HTJ2KEncoder.hpp". Any thoughts?

Thanks!!
