Improve change api (#628)

* fix: jsdoc comments

* more human casting of string values to boolean

* add coerceColour to get named colors to work

* cue can't pass isKeyOfType event check

* dont mutate value

* alloow cue in eventDef

* lint

* css named or hex formatting

* "sideEffects": false

* test colour hex regex

* roll eventDef back to master

* parse property

* don't export cssColour names

* remove import

* only allow string types to colour

* handle transparent colour

* mix alpha with bg colour

* only allow updating events

* descriptive names

* add test for getAccessibleColour

* readability
