Dclab

- ref: do not import missing features as zeros in fmt_tdms
- CLI:
- add tdms-to-rtdc converter "dclab-tdms2rtdc" (36)
- improve "dclab-verify-dataset" user experience
- Bugfixes:
- "limit events" filtering must be integer not boolean (41)
- Support opening tdms files with capitalized "userDef" column names
- OSError when trying to open files from repository root

- CLI: add rudimentary dataset checker "dclab-verify-dataset" (37)
- Add logic to compute parent/root/child event indices of RTDC_Hierarchy
- Hierarchy children now support contour, image, and traces
- Hierarchy children now support and remember manual filters (22)
- Update emodulus look-up table with larger values for deformation
- Implement pixel size correction for emodulus computation
- Allow to add pixelation error to isoelastics (`add_px_err=True`) (28)
- Bugfixes:
- Pixel size not read from tdms-based measurements
- Young's modulus computation wrong due to faulty FEM simulations (39)

- Remove all-zero dummy columns from dict format
- Implement hdf5-based RT-DC data reader (32)
- Implement hdf5-based RT-DC data writer (33)
- Bugfixes:
- Automatically fix inverted box filters
- RTDC_TDMS trace data contained empty arrays when no trace
data was present (trace key should not have been accessible)
- Not possible to get isoelastics for circularity

- New fluorescence crosstalk correction feature recipe (35)
- New ancillary features "fl1_max_ctc", "fl2_max_ctc", "fl3_max_ctc" (35)
- Add priority for multiple ancillary features with same name
- Bugfixes:
- Configuration key values were not hashed for ancillary features
- Code cleanup:
- Refactoring: Put ancillary columns into a new folder module
- Refactoring: Use the term "feature" consistently
- Unify trace handling in dclab (30)
- Add functions to convert input config data

- Bugfixes:
- Regression when loading configuration strings containing quotes
- Parameters missing when loading ShapeIn 2.0.1 tdms data

- Refactor configuration class to support new format (26)
