- 1D/2D/3d Lossy/Lossless Benchmark comparing TurboPFor Floating Point Compression to zfp & blosc.

- Several datasets with different distributions and from diverse fields used in the benchmark

- TurboPFor with 1D/2D/3D transpose with integrated xor+zigzag is compressing better and faster

- Lossy compression with pointwise relative error bound for extreme compression.
