Is your feature request related to a problem? Please describe.
It is often the case where the observations do not consist only of one function. Instead, observations can consist of mixed data, including several functions, multivariate data, or categorical variables.
In Python a common solution to store this kind of data are Pandas DataFrame objects. In order to support mixed or multivariate functional data, we need to integrate well with these.
Describe the solution you'd like
We need to:
[x] Allow to use functional data as the column type of a DataFrame, for all functional data representations.
[ ] Support receiving and emitting DataFrame objects in current and future estimators. At least a DataFrame with just one column should be accepted, and in most cases one could generalize them to accept more.
[ ] Document the feature in a section of the tutorial.
