Read the full context label array made by PyOpenJTalk correctly in HTS.load

[Hiroshiba]

I think hts.io.load can take argument of the full context label string lines.

nnmnkwii/nnmnkwii/io/hts.py

Line 165 in b716254

def load(self, path=None, lines=None):

This method eliminate the last character for deleting new line(in my understand).

nnmnkwii/nnmnkwii/io/hts.py

Line 184 in b716254

cols = line[:-1].split()

But, lines may have nothing new lines. (for example, PyOpenJTalk).

This PR will resolve this problem.
