Jeff Epler f22299d2b3 sdcardio: Use CMD25 across multiple writeblocks() calls 
This increases write rates (of gifio from #5490) from about 2.4fps to over
5fps by making more efficient use of the SD card protocol.

Because of details of oofatfs, it usually manages 64 writes in a single
CMD25, then two writes in a different area of the SD card (presumably,
filesystem metadata).  I couldn't find where to increase "64" to a higher
number. This may depend on the allocation size of the filesystem.

I tried preallocating too, but oddly it significantly lowered the write
rate.

Any trailing data is committed when the file is close()d, or when
the `sync` method of the SDCard object is called.

**CircuitPython** is a *beginner friendly*, open source version of Python for tiny, inexpensive
computers called microcontrollers.

This package contains the "stubs", or type definitions for CircuitPython.  With some advanced
editors and other tools, this information can be identify TypeErrors, AttributeErrors, and other
problems before you deploy your code to a device and can even help autocomplete your code.
