ENH Database support for tuples and list

[gadorlhiac]

Description

This PR adds database support for parameters which are tuples/lists. We assume, for the time being at least, that most parameters are not long tuples/lists. Therefore, they are handled by splitting the values and appending an index to the column keys in the database. A potential use case could be to have a single parameter which is a tuple representing a minimum and a maximum.
E.g. a["b"] in the nested dictionaries below:

outer = {
    "a": {
        "b": (1, 2),
        # ...
    },
    # ...
}

will have column keys of a.b[0] and a.b[1].
