TESTS: removed pp from installation test and reordered others
Moved ioSync source code to new repo

The actual ioSync Teensy 3 device source file and the piosync python
module have been moved to a new github project, isolver/iosync.

psychopy.iohub.mcu.iosync now uses this external package and only
contains the psychopy.iohub.mcu device interface code needed to use
ioSync as a device in psychopy.

To reflect changes in iosync python package ( github.com/isolver/iosync
)
