ENH: fixed failing test with macOS Rosetta emulation by increasing bu…

…ffer size

Increased buffer size from 1 MiB to 256 MiB.

Before this, on an arm64 Mac, this test would usually fail when run under Rosetta emulation. No idea why. Probably some caching effect, or other effect of emulation.  Making the buffer bigger seems to allow it to pass always.
