修复ubuntu 18.04的错误： “libpng12.so.0: cannot open shared object file: No such file or directory”

错误“libpng12.so.0: cannot open shared object file: No such file or directory”

运行ORB_SLAM3时，遇到错误“libpng12.so.0: cannot open shared object file: No such file or directory”。执行命令“sudo apt install libpng12-0”，可以按照libpng12.so.0，解决这个问题。
