RecordQueue: increasing queue depth
RecordQueue: increasing queue depth

Increasing queue depth from 53 (the value from the original Teensy Audio library?) to a depth of 100.  As we're often using this queue object to buffer while writing to an SD card, the deeper queue depth will perhaps let us handle the highly variable write timing seen in many SD cards.
