Dash-bio

Fixed
* [434](https://github.com/plotly/dash-bio/pull/434) Fixed FornaContainer selector issue, in which FornaContainer styles were being applied to all svg elements on the page.

Added
* [430](https://github.com/plotly/dash-bio/pull/430) Async AlignmentChart, Circos, Ideogram, Molecule2dViewer, Molecule3dViewer, NeedlePlot, OncoPrint, SequenceViewwer and Speck components

Added

* Added FornaContainer component for RNA secondary structure analysis.

Fixed

* Fixed AlignmentChart error in which `colorscale` being undefined
caused rendering to fail.
* Fixed AlignmentChart PropType for `eventDatum` to `string` (which is
what gets returned).
* Fixed Circos error in which `tracks` variable being undefined caused
rendering to fail.
* Fixed Clustergram error in which `display_ratio` (a float or a list)
was used as a list instead of `self._display_ratio`, which always
has the type `list`.
* Fixed Molecule2dViewer error in which `modelData` being undefined
caused rendering to fail.
* Fixed Molecule2dViewer PropType for `source` and `target` atoms
within the `links` property to also include `PropTypes.shape`.
* Fixed Molecule3dViewer error in which there was no re-rendering upon
a change in the `selectionType` prop.
* Fixed SequenceViewer error in which the component initially rendered
with coverage that had no defined `onClick` behavior.

Added

* Added re-rendering for Molecule2dViewer and Molecule3dViewer upon
the `selectedAtomIds` prop being updated. (This lets the user write
to the `selectedAtomIds` prop through a Dash component.)
* Added re-rendering for SequenceViewer upon the `coverageClicked`
prop being updated.

Removed

* Removed AlignmentViewer component
([414](https://github.com/plotly/dash-bio/issues/414))

Changed
* Updated core dependency to `dash>=1.0.0`.

Changed
* Renamed Clustergram parameters `hide_labels` and `symmetric_value` into
`hidden_labels` and `center_values` respectively.

Fixed
* Fixed issue with Molecule2dViewer not displaying triple bonds.
