Issue using LittleFS

[andyb2000]

Hi,
I've used this library for a while, however have now converted my scripts to LittleFS and found the library doesn't support it.
Can this be converted to use LittleFS since SPIFFS is being slowly removed throughout the esp8266 ecosystem.

Version: 2.1.1

Hi,

According to the docs it should be a drop in replacement. A PR would be appreciated here.
