Whitespace is not always stripped in Spectral Library table

[teutoburg]

Some spectral types are not found in the name column because trailing whitespaces are not stripped upon loading the table.

import pyckles
pickles = pyckles.SpectralLibrary("pickles", return_style="synphot")
"M25V" in pickles.table["name"]  # returns False
"M25V   " in pickles.table["name"]  # returns True

This leads to an AttributeError when trying to access via pickles["M25V"]. This issue not only exists for "M25V", but also for a number of classes ending in "_R" and "_W".
