Data loader for TOML

TOML data loader

Currently, we have a data loader for CSV files. It works by converting each data set (each row) to a namedtuple.

We need sth similar for TOML. Note that type conversion should be done as efficient as possible (see issue #63 for more information).

The loader should also handle non-consistent data, such as the TOML below:

[[employees.employee]]
name = "John Doe"
position = "Software Engineer"
salary = 80_000
children = 2

[[employees.employee]]
name = "Alice Smith"
position = "Network Administrator"
salary = 75_000
children = 1

[[employees.employee]]
name = "Bob Johnson"
experience = "Database"
wage = 82_000
car = "Audi"

Here, a LazyFileIterable containing three differently structured namedtuples should be created.
