Spell_Jam: Add word sounds

[RetiredWizard]

This is a fun little enhancement to the Fruit_Jam_Spell_Jam application. If you place either .wav or .mp3 audio files in the either the /apps/Fruit_Jam_Spell_Jam/spell_jam_assets/words (checked first) or /sd/spell_jam_assets/words the application will play the matching audio file after spelling the entered word.

I'm using it to add animal sounds so that when the word "cow" is entered the app says it, spells it and then moos like a cow. I found a couple web sites with free downloadable animal sounds but I plan to keep an eye out for AI models that might be used as well.

This could also be used if an AI model wasn't available, a parent could record a bunch of words and then the app would say the typed in word based on the file match rather than generating the audio of the word.

If you don't really want to continue to update the learn guide for this type of enhancement. I'm happy to update my playground instead. It obviously wouldn't automatically be bundled into Fruit Jam OS then though.....

This is really cool! Thanks for adding it.

I'm good with merging it here. I'll add a note to the guide about using this feature and mention that it's completely optional.

I tested successfully both words with and without an extra sound.
