Call to blocking method done in AsyncSpooledTemporaryFile.write coroutine

[cbornet]

AsyncSpooledTemporaryFile.write makes a call to blocking file.writelines (from my understanding the file may be a disk file if it reaches a certain size)

aiofiles/src/aiofiles/tempfile/temptypes.py

Line 53 in 3071526

rv = file.writelines(iterable)

This was detected while integrating BlockBuster. See #197

Actually this is a false positive.
Blockbuster has been fixed to handle SpooledTemporaryFile type of files
