Subject: [PATCH] feat: Add built-in to search keymaps (#191)

* Add built-in to search keymaps

* Re-factor maps for cleaner codes

Rather than use function to return a results table for various key maps.
Assign results the key maps table itself. This makes for cleaner code.

* Keymaps: escape termcodes using built-in util

* Rename builtin.maps to builtin.keymaps
