Fix inconsistent leading whitespace in libcalignedsegment.pyx
Fix inconsistent leading whitespace in libcalignedsegment.pyx

I want to work on this file, but have Sublime Text set up up to strip trailing whitespace on save, so did this first.

The whitespace-only lines don't seem to have a consistent style, so I'm pretty sure I'm not bulldozing over anyone's deliberate style choices with this change.
