<description>
An array specifically designed to hold bytes. Packs data tightly, so it saves memory for large array sizes.
[PackedByteArray] also provides methods to encode/decode various types to/from bytes. The way values are encoded is an implementation detail and shouldn't be relied upon when interacting with external apps.
