Read and write compressed ZGY

I'm looking for information on how to read a ZFP compressed ZGY file.

Writing compressed seems fairly simple. Just add .zfp_compressor(30) and .zfp_lodcompressor(50) to the IZgyWriterArgs and it appears to compress the output.

I have not found any comments or examples on how to read back the compressed ZGY file.

Can you point me in the right direction?
