Add parsing of command line arguments in presets

[osinenkop]

We need a call capability like:

python main_3wrobot_NI.py -ctrl_mode JACS -dt 0.01 ...

Required parameters:	Parameter name	Values	Notes
ctrl_mode	string	see description of methods in preset
dt	number	controller sampling time
t1	number	final time
x0	numpy vector	initial state, dimension preset-specific!

Optional parameters, set to default values unless specified otherwise:

Parameter name	Values	Default	Description
is_log_data	binary	0
is_visualization	binary	1
is_print_sim_step	binary	1
is_est_model	binary	0	if a model of the env. is to be estimated online
model_est_stage	number	1	seconds to learn model until benchmarking controller kicks in
model_est_period	number	1*dt	model is updated every model_est_period seconds
model_order	integer	5	order of state-space estimation model
prob_noise_pow	number	8	power of probing noise
uMan	numpy vector	zeros	manual control action to be fed constant, system-specific!
Nactor	integer	3	horizon length (in steps) for predictive controllers
pred_step_size	number	dt
buffer_size	integer	10
rcost_struct	string	quadratic	structure of running cost function
R1	numpy matrix	identity matrix	must have proper dimension
R2	numpy matrix	identity matrix	must have proper dimension
Ncritic	integer	4	critic stack size (number of TDs)
gamma	number	1	discount factor
critic_period	number	dt	critic is updated every critic_period seconds
critic_struct	string	quad-nomix	structure of critic features
actor_struct	string	quad-nomix	structure of actor features

This needs to be reflected in the readme, as an example call of an example present. Could probably be translated from this text.
