mo.ui.data_voyager

[mscolnick]

This adds mo.ui.data_voyager which is inspired by https://vega.github.io/voyager/.

It uses https://github.com/vega/compassql for chart recommendations and guides the user into exploring various charts and drilling down.

I expect a fair amount of back-and-forth comments on the UI/UX. There are also some features not added, but can be added in this PR if preferred:

• sorting
• scale (e.g. log)
• filtering a fields values
• grouping/filtering the types of recommendations (qualitative, temporal)
• stack offset for row/column encodings
• suggesting flipping encoding. currently all suggested are additive and we don't suggest replacements.

Things to note:

• we don't add all time fns, there are a lot. i am aiming to add the common ones
• The license from https://github.com/vega/voyager will need to be attributed, but we don't bring this library as a dep. The code from there has been simplified and modified, but still asks that we include the License.
