Henrik Lissner 050624d475 fix(lib): nested interpolation & order of args for fn! macro
This fixes a couple bugs with this macro:

- Nested %-refs (in nested fn!'s) were interpolated as arguments of the
  outer-most fn!. E.g. (fn! (fn! %2)) would expand to:

  Before this fix:

    (lambda (_%1 %2)
      (lambda (_%1 %2)
        %2))

  After this fix:

    (lambda ()
      (lambda (_%1 %2)
        %2))

- Unused arguments were not only listed in the wrong order, they were
  off-by-one. E.g.

    (fn! %3 %5) expands to (lambda (_%4 _%3 %3 _%1 %5) %3 %5)

  This never caused any actual issues, but it was unexpected.

I've also moved the lookup table to `fn!`, and removed unnecessary
entries from it.
