* feat: add box templates and box type
This commit adds an implementation of Boxes, memory manged heap
allocated values.
Boxes are implemented as C pointers, with no additional structure but
are treated as structs in Carp. To facilitate this, we need to add them
as a clause to our special type emissions (TypesToC) as they'd otherwise
be emitted like other struct types.

* fix: slight memory management fix for Box
Make sure we free the box!
* test: add tests for box (including memory checks)
* Revert "fix: Ignore clang nitpick"
This reverts commit 70ec6d46d4.
* fix: update example/functor.carp
Now that a builtin type named Box exists, the definitions in this file
cause a conflict. I've renamed the "Box" type in the functor example to
remove the conflict.
* feat: add Box.peek
Box.peek allows users to transform a reference to a box into a a
reference to the box's contained value. The returned reference will have
the same lifetime as the box. This function allows callers to manipulate
the value in a box without re-allocation, for example:
```clojure
(deftype Num [val Int])
(let-do [box (Box.init (Num.init 0))]
(Num.set-val! (Box.peek &box) 1)
@(Num.val (Box.peek &box)))
```
This commit also includes tests for Box.peek.

* feat: add quasiquote literals

* fix: fix errors with set!
Notably, don't type check dynamic bindings (which can be set to
whatever) and eliminate a hang that resulted from not handling an error
at the end of the `set!` call. Also refactors some of the code in
efforts to make it a bit cleaner.
Also adds an error when `set!` can't find the variable one calls set!

* Emit/Deftype: Add a few more special cases for Unit members
There were a few gaps remaining in our handling of Unit types as members
of user defined types, most notably, generic setters weren't handling
Units appropriately. This commit adds special checks for Unit types in
generic setters, and also accounts for a Unit refs:
- Specialize generic setter functions against Unit members
- Specialize calls to str/prn against Unit members in StructUtils
(rather than accessing the struct member, which doesn't exist in the
Unit case, we simple call Unit's prn function (added in the next
commit).
- Don't bind references to Unit values to variables. This fixes an error
whereby a reference to a Unit would generate invalid C such as:
`void* _9 = &;`
Likewise, we omit references to Units from function arguments just as
we omit Unit values.
* Unit: Add Unit type implementations for common interfaces.
Now that Unit can be used as a member type it is subject to several
interfaces, such as prn, that it previously hadn't implemented.
This commit adds Unit.carp to core which implements `prn`, `copy`, and
`zero` for the Unit type.
* Deftype: Return null pointers for Unit getters
This is *hopefully* one of the final updates needed to fully support
Unit's as member types. Getters for fields of such types have no struct
member to read, but are expected to return a void pointer; so we return
a NULL void pointer instead.
This commit also updates our emissions for function calls to prevent
assigning the results of functions with Unit and (Ref Unit) return types
to variables.
* Emit: Filter void args from lambda calls
Just as we filter void argument types from other function calls, we now
filter them from calls to lambdas.
+ Error values included are those that can be set from calling `fopen`
+ Change order of imports so that the System module is available before the IO module
