J. Nick Koston da5f67af69 Reduce logger UART RX buffer to minimum 
The logger only writes to UART, never reads. Previously it used
tx_buffer_size (512 bytes) for both RX and TX buffers. Since ESP-IDF
requires rx_buffer_size > UART_HW_FIFO_LEN (128), use the minimum
of 129 bytes instead of 512, saving ~383 bytes of heap.
