feat: enable serialization of enumerable and actions

[GeekyEggo]

Changes

• Update Enumerable to include a toJSON and toString implementation, allowing enumerables to be serialized.
• Update ActionContext, KeyAction, and DialAction to include getters when serializing.

Motive

When logging the streamDeck.actions, or this.actions within an action, nothing is logged. With Enumerable yielding results lazily, JavaScript does not evaluate the collection when formatting the logs as part of the JSON.stringify call. To resolve this, we can implement toJSON and toString functions on Enumerable.

With the aforementioned functions implemented, we now have actions logging, however the result looks something like this:

// streamDeck.logger.info(streamDeck.actions);
2025-01-03T18:54:11.131Z INFO  [{}]

This is caused by the KeyAction, DialAction, and ActionContext classes relying on getters for immutability. With toJSON implemented on these classes, we finally see a meaningful log entry:

// streamDeck.logger.info(streamDeck.actions);
2025-01-03T18:54:11.131Z INFO  [{"controllerType":"Keypad","device":{"id":"2d18b00bc2a0e9fd2073f1d2a1a0a2ed"},"id":"b2a6bb43802a330a41e3ab74e8a12e95","manifestId":"com.richard.test.action","coordinates":{"column":3,"row":1},"isInMultiAction":false}]
