More debugging of GPS parsing in task, still not working

Tried: - configuring to less than configMAX_SYSCALL_INTERRUPT_PRIORITY the priorities of IRQs which have handlers that use FreeRTOS API ISR-'safe' functions to <give> semaphores, queues - adding counters to see how many times the IRQ fired, and how many times the task fired - etc., etc.
