Change hard coded /tmp to cross-platform tempfile

Pardon me as I am not a Python expert. I installed Python and python-miio on Windows. When running the following command:

mirobo status

I received the following errors in addition to the proper output:

ERROR:miio.vacuum_cli:Unable to read the stored msgid: [Errno 2] No such file or
directory: '/tmp/python-mirobo.seq'
ERROR:miio.device:Got error when receiving: timed out

As a test I modified the following line in "vacuum_cli.py" from:

@click.option('--id-file', type=click.Path(dir_okay=False, writable=True), default='/tmp/python-mirobo.seq')

To:

@click.option('--id-file', type=click.Path(dir_okay=False, writable=True), default='c:\\python-mirobo.seq')

And now it works fine!

This needs to be fixed indeed, thanks for reporting, it's nice to know that it works on Windows too!

Just thought I would mention that I got around to upgrading from 0.3.3 to 0.3.5, and this fix works great on Windows!
