The aim of this project is to make you code a function that returns a line ending with a newline, read from a file descriptor.
Only 3 functions allowed to use from libc library: read, malloc, read. But it's possible to use functions from libft library.
In the header file get_next_line.h we must have at least the prototype of the function get_next_line and a macro that allows to choose the size of the reading buffer for the read function. That macro must be named BUFF_SIZE.
