Installing nlohmann-json3-dev is required

[dt1729]

Otherwise I see the error:

In file included from src/OPTTokenizer.cc:1: ./include/OPTTokenizer.h:22:10: fatal error: nlohmann/json.hpp: No such file or directory 22 | #include "nlohmann/json.hpp" | ^~~~~~~~~~~~~~~~~~~ compilation terminated. make: *** [Makefile:180: build/transformer/src/OPTTokenizer.o] Error 1 make: *** Waiting for unfinished jobs....

Fix:

sudo apt-get install nlohmann-json3-dev
