Type mismatch in `TinyString::operator+=(int)` - Declaration vs Implementation

[flohse123]

There is a type mismatch between the header declaration and the implementation of operator+= for integers in TinyString:

In TinyString.h (line 59):

TinyString& operator +=(int32_t);

In TinyString.cpp (line 75):

TinyString& TinyString::operator +=(int i)

This causes a compilation error:

error: no declaration matches 'TinyString& TinyString::operator+=(int)'

Fix:
Change line 75 in TinyString.cpp from:

TinyString& TinyString::operator +=(int i)

to:

TinyString& TinyString::operator +=(int32_t i)

Environment:

• Platform: ESP32 (Arduino framework)
• Compiler: xtensa-esp-elf-g++ 14.2.0

This simple type alignment fixes the compilation error.
