Content handler options not fully accessible

[nblumoe]

It's not possible to pass all the options down to the handler of specific formats to override for example decoder or predicate. This is because they are contained in a nested :options hash-map being created here:

ring-middleware-format/src/ring/middleware/format_params.clj

Line 278 in 3fd37b9

(wrapper h (assoc common-options :options (get format-options format)))

this does not override the top-level options via destructuring over here:

ring-middleware-format/src/ring/middleware/format_params.clj

Line 230 in 3fd37b9

(let [{:keys [predicate decoder binary? options] :as options} (impl/extract-options args)]

Thus, the calls like (or predicate transit-json-request?) will always end up with the second expression and cannot be overriden.
