Decrease binary dummy length

[item4]

fake.binary(length=1048576) generate too huge binary data but it is useless at docs build time.

I tested two case, 1048576 and 1024.

(faker) [item4@item4-mbp docs]$ echo "1048576"
1048576
(faker) [item4@item4-mbp docs]$ time make html
sphinx-build -b html -d _build/doctrees   . _build/html

Does docs really need 1048576 length binary?

I agree, does nothing except make docs load really slowly.
