Error compiling for board NodeMCU 1.0 | Solution

Hi guys

Very useful library you've provided here, Thanks a lot.
Code example : Countdown
The code compiles without any problem with Arduino Uno, But when it comes with ESP8266 i've got an error message :

C:\Users\Hamza\Documents\Arduino\libraries\ShiftDisplay\src\ShiftDisplay.cpp: In member function 'void ShiftDisplay::setAt(int, const byte*)':

C:\Users\Hamza\Documents\Arduino\libraries\ShiftDisplay\src\ShiftDisplay.cpp:353:61: error: invalid conversion from 'const byte* {aka const unsigned char*}' to 'byte* {aka unsigned char*}' [-fpermissive]

   modifyBuffer(_sectionBegins[section], sectionSize, customs);

                                                             ^

C:\Users\Hamza\Documents\Arduino\libraries\ShiftDisplay\src\ShiftDisplay.cpp:107:6: error:   initializing argument 3 of 'void ShiftDisplay::modifyBuffer(int, int, byte*)' [-fpermissive]

 void ShiftDisplay::modifyBuffer(int beginIndex, int size, byte codes[]) {

      ^

My ESP core version is 2.4.2 .

The solution i've tried (and thus succeeded) is to cast the parameter in the call to byte* as :

It's now compiles and runs without errors.
