The translation for billion (and others) is wrong in Spanish

[AndresRReina]

See here: https://github.com/python-humanize/humanize/blob/75abba2bcff904d6438c91a92bf1b50c6e243d12/src/humanize/locale/es_ES/LC_MESSAGES/humanize.po#L136

For example:

humanize.intword(12345591313)
'12.3 billones'

should have been "12.3 miles de millones"

Other multiples are also wrong (trillions, ...)
