[prozacchiwawa]

this creates an "assign" form that performs destructuring and binding a lot like let, but with simpler and more versatile syntax.

(mod (X)
  (include *standard-cl-21*)
  (defun-inline tup (X Y) (c X Y))
  (assign
    (X1 . X2) (tup (+ X 1) (+ X 2)) ;; 14
    X3 (+ X1 1) ;; 15
    X4 (+ X2 1) ;; 16
    (Y0 . X5) (tup (+ X4 1) (+ X4 1)) ;; 17
    X6 (+ Y0 1) ;; 18
    Y1 (+ X6 Y0) ;; 35
    Y1
    )
  )

Ordering is done automatically and the bindings are broken up into a stack of parallel let forms.

Need to add additional tests in here, bug based on feedback.

[prozacchiwawa]

not actually a bug but adding tests surrounding this.
i'm going to push strict mode harder.

https://github.com/Chia-Network/clvm_tools_rs/pull/124 <-- this bug was found, which is unrelated to this code, but is exercised by it.
