* Check if closed

* remove a few logs

* r

* fix `isValid` and `isReady`

* Add JImage

* Release JNI frame ref on destroy

* fix pod setup

* Fix isValid call

* Fix `close` not returning a function

* throw error if closed twice

* iOS: Schedule `console.error` call on JS thread

* Android: Log Frame Processor Error to JS

* fix syntax

* Check if valid `toString()`

* Update Frame.ts

* Remove `isReady`

* Fix JImage accessors

* remove `JImage` C++ sources

* Throw error if accessing props on closed Frame
