Option to disable arity checks

[borkdude]

user=> (sci/eval-string "(defn f [a b c] 1) (f)" {:disable-arity-checks true})

user=> (sci/eval-string "(defn f [a b c] [a b c]) (f)" {:disable-arity-checks true})
[nil nil nil]

For multi-arity fns this needs more thought:

multi-arity functions should be handled differently probably:
cljs.user=> (defn foo ([a] 1) ([a b] 2) ([a b & cs] :varargs))
#'cljs.user/foo
cljs.user=> (foo)
            ^
WARNING: Wrong number of args (0) passed to cljs.user/foo at line 1
:varargs
cljs.user=> (defn foo ([a] 1) ([a b] 2))
#'cljs.user/foo
cljs.user=> (foo)
            ^
WARNING: Wrong number of args (0) passed to cljs.user/foo at line 1
Execution error (Error) at (<cljs repl>:1).
Invalid arity: 0
