HDF5 settings: chunking, compression etc.

[gipert]

• [ ] Decide if we want to keep using our custom waveform compressors or just an HDF5 filter (e.g. GZIP)
• [ ] Decide on the HDF5 filter for the higher tiers: GZIP is old and slow, can we use SZIP (builtin since HDF5 v1.6)?
• [ ] Should we run bit shuffle first?
• [ ] What is the optimal chunk size for higher tier data?
