Correct negative field values

[ramirezdiego]

Not directly a fuse issue, but currently we have this piece of code to prevent crashes:

fuse/fuse/plugins/micro_physics/electric_field.py

Lines 70 to 74 in 559616f

	# Clip negative values to 0
	n_negative_values = np.sum(electric_field_array['e_field'] < 0)
	if n_negative_values > 0:
	log.warning(f"Found {n_negative_values} negative electric field values. Clipping to 0.")
	electric_field_array['e_field'] = np.clip(electric_field_array['e_field'], 0, None)

Let's make sure the loaded maps have the bining and format necessary so that we do not need this hack.

Applies also for clipping added in #140.
