Delta encoding

[DomGries]

Tests show that using delta encoding on my serialized data before compressing reduces file size.

According to https://libraries.io/github/fraillt/bitsery delta encoding might have already been planned:

[bitsery] is still missing functions for delta changes and geometry compression

How would I best implement delta encoding in Bitsery?

EDIT: After separating serialize into save/load functions by not using the quickSerialization function it's now clear how to do this manually.

Very good point, bitsery indeed is missing delta serialization functions, but this is a broader topic than I initially was expected. Actually bitsery was born from delta serialization, which later was removed entirely for multiple reasons. For curiosity, you can look at first commit.
There were classes like DeltaSerializer and DeltaDeserializer.
Now I think that delta encoding should be done as a separate library, some parts of bitsery could be reused, like Input/OutputAdapter, etc...
Could you elaborate more on how you gonna do delta encoding for your needs?
