void ConfigTdmSlot (uint8_t bit_offset, uint8_t num_slots, uint8_t bits_per_slot, uint8_t bits_per_sample, uint8_t mix_mask, bool i2s_mode)bit_offset - bit position in frame where first slot will appear
(position 0 is concurrent with frame sync)
num_slots - number of slots per frame minus one
bits_per_slot - width of each slot minus one
bits_per_sample - number of bits in sample minus one
mix_mask - lanes to mix L+R.

starts the tdm to clock out data on the bus
returns the start time
