Enable processing of AMML parameters as iterables

Currently, certain operations, such as queries and filters can only be applied to the iterables Table and Series. However, there is a bunch of further iterable parameters, such as Species, Reaction, Structure, Calculator, Algorithm, Property and Trajectory. The goal is to enable the same common syntaxes for these latter parameters.

The current grammar allows this use but the constraints and the interpreter have to be adapted.

Example:

water = Species H2O (
    (free_energy: -14.739080832009071, -14.994145508249682) [eV],
    (temperature: 500., 600.) [K]
)
free_at_500_K = water select free_energy where temperature == 500. [K]
water_props_query = water where free_energy < -14.994145508249682 [eV]
