Dependency name 'stdlib' found, but expected 'dp-stdlib' instead

@zoziha thanks for lightweight stdlib. I was following the instructions in README.md and ran into issue

fpm build
…
From https://github.com/zoziha/dp-stdlib
 * branch            HEAD       -> FETCH_HEAD
<ERROR>*cmd_build*:model error:Dependency name 'stdlib' found, but expected 'dp-stdlib' instead
STOP 1

I think this will work:

• change the library name in fpm.toml, or
• change the library dependency name in README.md

Yes, this is dp-stdlib that I put together temporarily yesterday, and it has this problem.
I've just tried to solve the existing problems, and stdlib_random is probably unsafe (incorrect) right now, I'm going to keep an eye on it.
