Merge tag 'v0.9.0' into debian

Various improvements and compatibility/support (dcm2niix, datalad,
duecredit) changes.  Major change is placement of output files to the
target output directory during conversion.

- #454 zenodo referencing in README.rst and support for ducredit for
  heudiconv and reproin heuristic
- #445 more tutorial references in README.md

- [#485][] placed files during conversion right away into the target
  directory (with a `_heudiconv???` suffix, renamed into ultimate target
  name later on), which avoids hitting file size limits of /tmp ([#481][]) and
  helped to avoid a regression in dcm2nixx 1.0.20201102
- #477 replaced `rec-<magnitude|phase>` with `part-<mag|phase>` now
  that BIDS supports the part entity
- #473 made default for CogAtlasID to be a TODO URL
- #459 made AcquisitionTime used for acq_time scans file field
- #451 retained sub-second resolution in scans files
- #442 refactored code so there is now heudiconv.main.workflow for
  more convenient use as a Python module

- minimal version of nipype set to 1.2.3 to guarantee correct handling
  of DWI files ([#480][])
- `heudiconvDCM*` temporary directories are removed now ([#462][])
- compatibility with DataLad 0.13 ([#464][])

- #443 pathlib as a dependency (we are Python3 only now)

* tag 'v0.9.0':
  Do no bother ensuring that version changed - should be no changes
