SPI lock not aquired

Problem

adafruit_esp32spi.py throws the below RuntimeError

Traceback (most recent call last):
  File "code.py", line 21, in <module>

RuntimeError: Function requires lock

How to reproduce

1. Play a sound file from an sd card (via SPI) with audioio.AudioOut
2. Without waiting for it to finish, use adafruit_requests (which uses adafruit_esp32spi/adafruit_esp32spi_socket)

Inspecting the error, I would guess that _read_byte should be acquiring a lock on the SPI bus, which is being used to play audio (with DMA if I had to guess).
