Include a native Python dict read function

[AdrianDAlessandro]

Since the most basic version of this package only requires the pyyaml dependency, there should be a basic read function that returns a native Python type.

There is currently a read_to_list function (that isn't exposed as a top-level function), that returns a nested list. But that isn't in the most developer friendly format because it has a mix of column headers and data in the list. A dictionary type feels more appropriate.

The dictionary could be structured with 2 keys, "columns" and "data", with "data" being a 2D nested list. Or it could have the columns names as keys and the values each being a list for that column.
