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

If django.utils.numberformat.format() – used by contrib.admin as well as the \ 
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.
