Error propagation UI

[estebanuribe]

Propagate errors from Rust to Swift via GiphRSError

[saik0]

This gets translated by UniFFI to GiphRsException which is an Exception

[estebanuribe]

Is this redundant then? Should I remove this function?

[estebanuribe]

Fix this, should be GiphRSException now.

See:

giphrs/android/core/src/main/java/com/joelpedraza/giphrs/core/GiphRsErrorExtensions.kt

Lines 9 to 22 in 7c29612

	fun GiphRsException.toException(): Exception {
	return when (this) {
	is GiphRsException.NetworkException ->
	IOException("Network Error: ${this.message}")
	is GiphRsException.ParseException ->
	IllegalStateException("Parse Error: ${this.message}")
	is GiphRsException.ApiException ->
	Exception("API Error: ${this.message}")
	is GiphRsException.Unknown ->
	Exception("Unknown Error: ${this.message}")
	}

This should follow the pattern of having an accessor and a polling function for changes it should be updated to return Option<GiphRsError>

However, this introduces an issue as a stream's terminal state is indicated by a None value. We could get around it by adding a GiphRsError.None enum value

[estebanuribe]

I went ahead and created GiphRsErrorState to avoid having a None state in GiphRsError which based on research appears to be an anti-pattern. Updated iOS and Android with the new enum, was able to build on both now!!!!
