New option to pass through HugSQL options

[nottmey]

To my knowledge it is currently not possible to make use of the options parameter of the encapsulated hugsql.core/def-db-fns function (docs) when using conman.core/bind-connection to set connection specific configurations.

I propose the use of an options map for bind-connection, similar showcased and helpful in #19, which is then handed to def-db-fns.

In my case I need to enable :quoting (:mysql) for HugSQL functions per default. Currently this is solved by always providing the database and options map for each call of a generated HugSQL function (example in first snippet), which is far from ideal (second snippet), since connection aware functions are one key feature of conman.

(db/get-user *db* {:id "foo"} {:quoting :mysql})

(db/get-user {:id "foo"})

That sounds reasonable to me, would you by any chance be up for doing a pr? :)
