FFI shared libraries load/run

[rd4com]

its quite easy to use as provided by mojo already, but i made the smallest wrapper ever written anyway

https://github.com/rd4com/mojo-learning/tree/main/FFI%20shared%20libraries%20load%20and%20use

var lib = lib_loader("./lib.so")
var my_func = lib.get[fn(Pointer[Int8])->Int]("my_func")

var ptr = Pointer[Int8]().alloc(5)
var int_result = my_func(ptr)

print("hello "+String(ptr,5))
print(int_result)
