Micropython implementation of DFPlayer control using UART 1 (secondary Serial connection) on ESP8266

If you are not limited to ESP8266 (with its TX-only UART) you should consider using https://github.com/jczic/KT403A-MP3/blob/master/kt403A.py instead.

To use, wire up the DFPlayer Mini MP3 breakout module following this loom...

![alt text](550px-Miniplayer_pin_map.png)

* DFPlayer Mini

    * VCC           => 5V Vin

    * All GND pins  => GND

    * Busy Pin (immediately opposite VCC) => GPIO2 (NodeMCU D3)

    * RX Pin (immediately below VCC)      => GPIO0 (NodeMCU D4)

    * SPK1+SPK2 to a 3W speaker (limiting the volume to 0.5 can help prevent brownout for larger wattage speakers)

    * ...or...

    * DAC_R+DAC_L to a 3.5mm Line Out Jack

The following example code uses the ScanPlayer. 

It will first scan all available folders for files called 000_XXX.mp3 001_XXX.mp3 and so on.

It considers only folders named 00-09.

It will play a single track from each folder in turn, only repeating a folder 

when all folders are exhausted, and only repeating a track when all tracks have been exhausted. 

```python

from time import sleep

import scanplayer

player = scanplayer.ScanPlayer()

availableFolders = list(player.tracks.keys())

if len(availableFolders) > 0:

    keyPos = 0

    while True:

        folder = availableFolders[keyPos]

        player.playFolder(folder)

        while player.playing():

            sleep(0.1)

        keyPos = (keyPos + 1) %  len(availableFolders)

else:

    print("No available tracks")

```
