Roadmap: workflows support for sparse tibbles

[EmilHvitfeldt]

What we need:

• fit() to take sparse tibbles as data test that sparse tibbles work in fit() #245
• fit() to take {Matrix} sparse matrix as data test that sparse matrices work with fit() #258
  • turn them into sparse tibbles early
• predict() to take sparse tibbles as data Make predict() work with sparse data #261
• predict() to take {Matrix} sparse matrix as data Make predict() work with sparse data #261
  • turn them into sparse tibbles early

Adding all of this will give us:

• everything it needs to be able to work with the rest of {tidymodels} in regards to sparse tibbles
