paredit api should accept both map and vector for pos arguments

[lread]

Problem/Opportunity
The paredit API has some fns that accept a pos argument.
It expects pos to be expressed as a map with :row and :col keys.
The paredit ns came from rewrite-cljs so the history/compatibility makes sense.

But rewrite-clj expresses position as a vector [row col] as a return from rewrite-clj.zip/position.
And allows for both the map and vector syntax for pos arg for rewrite-clj.zip/find-last-by-pos and rewrite-clj.zip/find-tag-by-pos.

Proposed Solution
In addition to map, also accept vector [row col] for pos for paredit pos args:

• kill-at-pos
• kill-one-at-pos
• split-at-pos

Alternative Solutions
Nada

Additional context
None

Action
I will make it so
