add convert arg to int

[zh3036]

when user provides a arg in
lq [query_name] [args]

prev behavior is to treat args as strings
now it attempts to convert to int when possible(and leaves it as it is when failed)

the change is useful when you want to have db-id as args

for example ,

 :lq/block-content
 {
     :query            [:find (pull ?b [*])
                        :in $ ?parent
                        :where
                        [?b :block/parent ?parent]]
     :inputs           [:parent]
 }

for this query i run run
lq block-content 1577

previously it finds nothing because it treats 1577 as "1577"
not it finds the content because it treats 1577 properly as db/id
