Only use `input.forcing` in the TOML file (removed list of internal forcing variables below `input.dynamic` entry).

Only use `input.cyclic` in the TOML file (removed `input.dynamic` entry).

For function `lens_input_parameter` as it is not possible to distinguish between cyclic or static model input parameter.

Error thrown for functions `lens_input_parameter` and `lens_input` for required input model parameters but not set in TOML file.

A bit more strict. For example for output, check if all required TOML sections are set. For states reading check if state section in TOML file is complete.

More explicit, all starting with `output` including info on file format/data type (scalar or grid for netCDF).
