Hi,

I'm trying to implement a VDB parser for a personal engine without using the OpenVDB library because it is quite large and has many dependencies. I found your repository, which is easier to understand than the original, and I must say that I am very impressed with your work.

While looking at the BufferIteration class, I think I found a bug in your code. Specifically, when you call precision.size, I believe you meant precisionLUT.size. I have debugged it, and precision.size returns undefined, but it does not break the execution. I don't know if I am right or not, but I thought it was a good idea to let you know.

Cheers,
