Write the function void emoji$\_$init:

In emoji$-$translate.c$,$ you will find four functions:

void emoji$\_$init$($emoji$\_$t $*$emoji$)$ is called to initialize an emoji object.

void emoji$\_$add$\_$translation$($emoji$\_$t $*$emoji$,$ const unsigned char $*$source$,$ const unsigned char $*$translation$)$ adds a translation to the emoji object. For example, $$ might translate to diamond.

const unsigned char $*$emoji$\_$translate$\_$file$\_$alloc$($emoji$\_$t $*$emoji$,$ const char $*$fileName$)$ must translate the contents of the file specified by fileName using all translation rules added so far. When matching rules, always choose the longest matching rule based on the length of the source.
