free: implement --wide

[sylvestre]

       -w, --wide
              Switch to the wide mode. The wide mode produces lines longer than 80 characters. In
              this mode buffers and cache are reported in two separate columns.

This seems already implemented https://github.com/uutils/procps/blob/main/src/uu/free/src/free.rs#L84

[sylvestre]

is it correctly implement? i am not sure :)

[claudex]

I don't see the difference, maybe I'm missing something:

$ /bin/free -w
               total        used        free      shared     buffers       cache   available

$ target/release/free -w

I think this feature should be implemented correctly

Hi, I’d like to work on this if it’s still available.

@r3yc0n1c to me it looks like it's implemented as mentioned by @claudex . Maybe @sylvestre / @Krysztal112233 can provide more information about what's incorrect?
