Compiling under ARM7 GCC compiler report these warning:
image-encoders.cpp: In function 'int lz4_usr_more_space(Lz4EncoderUsrContext*, uint8_t**)':
image-encoders.cpp:261:32: error: cast from 'Lz4EncoderUsrContext*' to 'Lz4Data*' increases required alignment of target type [-Werror=cast-align]
261 | EncoderData *usr_data = &(((Lz4Data *)usr)->data);

image-encoders.cpp: In function 'int lz4_usr_more_lines(Lz4EncoderUsrContext*, uint8_t**)':

In all other occurrences of these cast we are already using
