Use simple growth scale with any max size for BufferedRowResultProxy
The maximum buffer size for the :class:`.BufferedRowResultProxy`, which
is used by dialects such as PostgreSQL when ``stream_results=True``, can
now be set to a number greater than 1000 and the buffer will grow to
that size. Previously, the buffer would not go beyond 1000 even if the
value were set larger. The growth of the buffer is also now based
on a simple multiplying factor currently set to 5. Pull request courtesy
