Fix get_channel_energy_values for SOHO/EPHIN electrons

[jgieseler]

get_channel_energy_values() is causing problems for SOHO/EPHIN electrons, before and after the change in data product on Oct 4, 2017. The return array has a length of 4 or 5, depending on time. But actually it should be be 3 or 4. The problems lie in

SEPpy/seppy/tools/__init__.py

Lines 2270 to 2274 in 2ff9cb8

	if self.sensor.lower() == "ephin":
	# Choose only the 4 first channels / descriptions, since I only know of
	# E150, E300, E1300 and E3000. The rest are unknown to me.
	# Go up to index 5, because index 1 is 'deactivated bc. of failure mode D'
	energy_ranges = [val for val in self.current_energies.values()][:5]

and

SEPpy/seppy/tools/__init__.py

Lines 2335 to 2339 in 2ff9cb8

	# Sometimes there is no hyphen, but then it's not a range of energies
	try:
	lower_bound, temp = energy_str.split('-')
	except ValueError:
	continue

First, it's truncated wrongly. Second, after the change of the data product, one channel info changed to 'deactivated bc. of failure mode D', which cause that channel to be skipped in the second code example above.

Has this been fixed with jgieseler@5d9eb6b?

The pull request 52 (#52) should address this.
