VS10xx Driver for MicroPython

This is an adoption of the great work for the VS1053 by Uri Shaked for CircuitPython here.

My board is a VS1003B and the code is working, therefore I'd rather call it a VS10xx library.

Sample wiring

VS1003B Board	ESP32 PIN	Signal
5V	5V	VCC
GND	GND	Ground
XRST	GPIO21	Reset (Active Low)
MISO	GPIO12	Master In Slave Out
MOSI	GPIO13	Master Out Slave In
SCLK	GPIO14	SPI Clock Signal
DREQ	GPIO22	Data Request
XCS	GPIO25	Send Command (Active Low)
XDCS	GPIO23	Send Data (Active Low)

Sample code for the ESP32 board

import vs10xx
from machine import SPI

spi = SPI(1, vs10xx.SPI_BAUDRATE) # SPI bus id=1 pinout: SCK = 14, MOSI = 13, MISO = 12

player = vs10xx.Player(
    spi,
    xResetPin = 21,
    dReqPin = 22,
    xDCSPin = 23,
    xCSPin = 25,
    CSPin = None
)

# copied a test.mp3 directly to the esp32 filesystem via WebREPL
inputFile = open('test.mp3', mode='rb')

buf = bytearray(32)
while inputFile.readinto(buf):
    player.writeData(buf)
