comparison of different sizes

I still cannot install it in the clusterm, but I tried in my laptop and after updating Rcpp to 1.0.13 it works but it gives me a warning ``` tesseract.cpp: In function ‘Rcpp::List engine_info_internal(TessPtr)’: tesseract.cpp:115:23: warning: comparison of integer expressions of different signedness: ‘size_t’ {aka ‘long unsigned int’} and ‘int’ [-Wsign-compare] 115 | for(size_t i = 0; i < langs.size(); i++) | ~~^~~~~~~~~~~~~~ tesseract.cpp:120:23: warning: comparison of integer expressions of different signedness: ‘size_t’ {aka ‘long unsigned int’} and ‘int’ [-Wsign-compare] 120 | for(size_t i = 0; i < langs.size(); i++) | ~~^~~~~~~~~~~~~~ ```
