[Feature Request] Command dependency tree.

[Borwe]

Wanted to have like a Tree structure for Nob_Cmd, which allows them to be dependent on each other eg:

    A
/       \
B      C

So we can build a tree, where B and C depend on running after A, maybe also an async_run support for the tree, whereby B and C can run concurrently as they don't depend on each other.

You can do this in base nob.h in c. For example:

Nob_Cmd cmdA = {};
nob_cmd_append(&cmdA, "a", "specific", "command");
if (nob_cmd_run(&cmdA)) {
    Nob_Cmd cmdB = {};
    nob_cmd_append(&cmdB, "command", "B", "stuff");
    Nob_Cmd cmdC = {};
    nob_cmd_append(&cmdC, "command", "C", "stuff");
    Nob_Procs procs = {};
    nob_cmd_run(&cmdB, .async = &procs);
    nob_cmd_run(&cmdC, .async = &procs);

    nob_procs_wait(procs);
}

If you want to run this multiple times in a single nob execution, then you would factor it out into a function and call that as many times as you want. This will also allow passing in variables, increasing reusablity.

Do you have a use case for this functionality that prompts creating a script structure inside of nob rather than using nob directly?
