Webknossos

Breaking Changes
- `BoundingBox.chunk()`'s 2nd parameter `chunk_border_alignments` now does not accept a list with a single `int` anymore. [437](https://github.com/scalableminds/webknossos-libs/pull/452)

Fixed
- Make Views picklable. We now ignore the file handle when we pickle Views. [469](https://github.com/scalableminds/webknossos-libs/pull/469)

Added
- Added a new Annotation class which includes skeletons as well as volume-annotations. [437](https://github.com/scalableminds/webknossos-libs/pull/452)
- Added dataset down- and upload as well as annotation download, see the examples `learned_segmenter.py` and `upload_image_data.py`. [437](https://github.com/scalableminds/webknossos-libs/pull/452)

Changed
- `View`s now always open the `wkw.Dataset` lazily. All explicit calls to `View.open()` and `View.close()` must be removed. [448](https://github.com/scalableminds/webknossos-libs/pull/448)
Fixed
- Fixed two bugs in `cubing` (regarding `start_z` and `pad`). As a result, the ImageConverters do no longer cache metadata. [460](https://github.com/scalableminds/webknossos-libs/pull/460)

* [wkcuber] Make tiff and czi reading more robust by youri-k in https://github.com/scalableminds/webknossos-libs/pull/335
* Allow float numpy array in BoundingBox.contains by fm3 in https://github.com/scalableminds/webknossos-libs/pull/450
* Forbid implicit optional in typing by fm3 in https://github.com/scalableminds/webknossos-libs/pull/449
* Use Dataset API inside `cubing` by rschwanhold in https://github.com/scalableminds/webknossos-libs/pull/418


**Full Changelog**: https://github.com/scalableminds/webknossos-libs/compare/v0.8.17...v0.8.18

wkcuber and webknossos:
- Updated scikit-image dependency to 0.18.3. 435

wkcuber:
- Add jp2 support. [428](https://github.com/scalableminds/webknossos-libs/pull/428)
- Fixed the string translation for `signed int` layer. [428](https://github.com/scalableminds/webknossos-libs/pull/428)

webknossos python lib:
- Refactored the BufferedSliceWriter and added a BufferedSliceReader. [425](https://github.com/scalableminds/webknossos-libs/pull/425)
- Breaking changes in BufferedSliceWriter:
- The data no longer gets transposed: previously the format of the slices was [y,x]; now it is [x,y]
- The interface of the constructor was changed:
- A `View` (or `MagView`) is now required as datasource
- The parameter `dimension` can be used to specify the axis along the data is sliced
- The offset is expected to be in the magnification of the view
- This class is now supposed to be used within a context manager and the slices are written by sending them to the generator (see documentation of the class).
- BufferedSliceReader
- This class was added complementary to the BufferedSliceWriter
- Added methods to get a BufferedSliceReader/BufferedSliceWriter from a View directly

Fixed an indexing bug in `webknossos.geometry.BoundingBox.to_slices()` introduced in v0.8.15.
