The build is failing due to pylint failing to run (e.g. [here](https://app.circleci.com/pipelines/github/plotly/dash-pivottable/32/workflows/b4009601-372b-4239-8c63-6e47b1897139/jobs/86/parallel-runs/0/steps/0-106)) which is due to [this restriction on asteriod](https://github.com/plotly/dash-pivottable/blob/master/tests/requirements.txt#L8). If I remove that line then pylint locally runs fine.

@chriddyp any chance you could help move this PR along?

> I applied your changes for my pivot table but I filter my columns or rows, the valueFilter argument is still empty on my callbacks. Does it work for you...

Well that's not great and suggests an improvement is needed on this PR. However, there's little point in me doing that given it's totally stalled
