implemented binary_grid-style statistics over last n_logging_stats verbose outputs (50 by default)

added ANSI colour to output if in a terminal (i.e. with a tty)

fixed the cmd-line parser to work in the form x=y as intended (downside: no help output, but that just said how to use the old parser which doesn't exist now)

add option such that when resolution==0, the resolution is calculated automatically from the sample list.

add delete_grid_variable function

In my CEMP simulations, I use the above with something like this to zoom in around 0.8Msun in M1:

emp_population.update_grid_variable(
    name="lnm1",
    spacingfunc="gaussian_zoom(np.log(0.4),np.log(6.0),np.log(0.8),0.05,0.99,100)",
    resolution=0
)

shows:
current grid status (#/# and modulo)
estimate of time remaining and time to finish
memory use (of all processes)
time per run

Integrated the new functions, population_id will now be renewed upon running a grid, prevented evolve_single from running if there are no arguments passed, added some check in the export_all_info function that raises an error if the user tries to export without outfile OR data_dir

Fixed some complaints that pylint had and fixed a correct mass ratio lower bound in the interpolators

Working on the M&S: almost done with everything. Just need to get the stuff right from multiple multiplicities in 1 run

Working on the M&S grid now: added alot of verbose output, and making sure all the interpolators are freed. Now I need to add the eccentricity as options and output for plots. Also reformatted
