apa102: avoid creating garbage
...
Avoid creating unnecessary garbage in the following ways:
* Use the Transfer method instead of the Tx method for single byte
transfers.
* Use a statically allocated buffer for the fixed start-of-frame
sequence.
Running this for a few minutes did not cause the garbage collector to
run. Previously, it would run every second or so in a
persistence-of-vision application.
