Filtering using `in` operator doesn't work as expected

Bug Report

Steps to Reproduce:

1. Display trade data using PerspectiveWidget
2. Filter account == 'STAN2', table correctly updates showing only STAN2
3. Filter account == 'STAN4', table correctly updates showing only STAN4
4. Change filter to in, no change as in ['STAN4'] is equivalent to == 'STAN4'
5. Change to in ['STAN4', 'STAN3'] No Change! 🐛
6. Confirm 🐛 by changing to in ['STAN5', 'STAN3'] again No Change - table still shows only STAN4 trades.

Actual Result:

Environment:

Running perspective 0.10.0 in an ubuntu linux container with ipywidgets 7.6.3 running in JupyterLab 3.1.6

Might be related to #1517?

This looks like an issue with recent refactors of perspective-viewer, specifically the Filter enum in view_config.rs, which fails when given a non-scalar type.

This issue will be fixed in the new perspective-viewer before the next release.

As a temporary workaround, the in filter should work in Perspective 0.9.0. Thanks for the report!

@texodus both in and not in are broken in master - both trace back to view_config.rs as being the issue.
