Ayke van Laethem 91539d9ef8 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.
