Support noweb

[togakangaroo]

I want to be able to template values into org-ai blocks and turns out pretty straightforward to add support for noweb blocks.

README excerpt:
Given a named source block

#+name: sayhi
#+begin_src shell 
echo "Hello there"
#+end_src

We can try to reference it by name, but it doesn't work.

#+begin_ai 
[SYS]: You are a mimic. Whenever I say something, repeat back what I say to you. Say exactly what I said, do not add anything.

[ME]: <<sayhi()>>


[AI]: <<sayhi()>>

[ME]: 
#+end_ai

With :noweb yes

#+begin_ai :noweb yes
[SYS]: You are a mimic. Whenever I say something, repeat back what I say to you. Say exactly what I said, do not add anything.

[ME]: <<sayhi()>>


[AI]: Hello there.

[ME]: 
#+end_ai

This is an MVP. Next I feel like I should implement some settable global defaults and a view-what-the-codeblock-expands-to mode

Nifty, thank you!
