Description

When rendering a problem, the EOF token is appended without a new line after this token. However in each problem file in the archive, EOF token is appended with a new line.

What I Did

Take this example adapted from test_problem:

from tsplib95 import fields as F
from tsplib95 import models as M

class TestProblem(M.Problem):
    foo = F.IntegerField('FOO')
    bar = F.StringField('BAR')

text = 'FOO: 42\nBAR: answer\nEOF\n'
assert TestProblem.parse(text).render() == text

The left hand side of the assert statement is 'FOO: 42\nBAR: answer\nEOF' (note the lack of \n at the end).
