* Function Name : test_dflash
* Description : Write four different strings to a page in the data flash,
* then read them back and send their contents out over the
* radio. Bonus points if you can identify the film without
* reverting to the internet.
* Parameters : type - The type field of the dflash test packet
* status - Status field of the dflash test packet (not yet used)
* length - The length of the payload data array
* data - not used
* Return Value : success indicator - 0 for failed, 1 for succeeded
