Clean text from color escape sequences
In order to handle end-of-buffer reads with partial line chunks, merge those when cleaning text. Pass each line then to the offset extracting function which gathers begin/end offsets of escape sequences. Finally, for printing cleaned lines of text, omit all color escape sequences as defined by their set of offsets (and restore characters temporarily overwritten with terminating NUL). Furthermore, add a basic string concatenation function and wrap the free memory function to have it nullify pointers.
