Compile fails w/ Arduino IDE v1.8.10

[schneis]

I'm just getting started with this and am stumbling thru getting the Arduino environment setup.

I cloned this library and when trying to compile the example sketch, I get the following errors:

Arduino: 1.8.10 (Linux), Board: "Generic ESP8266 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), dtr (aka nodemcu), 26 MHz, 40MHz, DOUT (compatible), 1MB (FS:64KB OTA:~470KB), 2, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

This report would have more information with

option enabled in File -> Preferences.

The following patch seems to resolve the issue:
