CVE-2019-6975: Memory exhaustion in django.utils.numberformat.format()

If django.utils.numberformat.format() -- used by contrib.admin as well as the floatformat, filesizeformat, and intcomma templates filters -- received a Decimal with a large number of digits or a large exponent, it could lead to significant memory usage due to a call to '{:f}'.format().

To avoid this, decimals with more than 200 digits are now formatted using scientific notation.
