Dclab

- enh: support reading 'tables' from DCOR datasets (221)

- enh: support reading 'logs' from DCOR datasets
- enh: hierarchy parents inherit their parent's logs and tables

- feat: support opening objects on S3-compatible storage (213)
- feat: support opening file-like objects as HDF5 data
- enh: use regexp to identify valid DCOR URLs
- enh: allow to pass keyword arguments to h5py.File for fmt_hdf5

- fix: do not recompute inert_ratio_cvx and inert_ratio_raw
computed with Shape-In >= 2.0.5 (224)
- tests: add additional test for inertia ratio (223)

- feat: implement `is_properly_compressed`, `rtdc_copy`, and
`h5ds_copy` in `dclab.rtdc_dataset.copier` (216)
- feat: support "tables" (compound arrays) in HDF5 files
- fix: explicitly use 64bit ints and floats when instantiating numpy
arrays, because numpy on Windows defaults to 32bit ints
which resulted in overflows when computing inertia ratio
- enh: unify names of exported logs
- enh: CLI use `rtdc_copy` in dclab-compress, dclab-condense,
and dclab-repack (216)
- enh: CLI compute the command log as early as possible
- enh: ignore "def" feature when performing an unknown-feature check
- enh: minor improvements in error message verbosity here and there
- ref: remove deprecated method dclab.load.check_dataset

- enh: CLI new --no-ancillary-features keyword argument for
dclab-condense to skip the computation of expensive features
