[ChunkCodecCore] BREAKING make can_concatenate a decoder method

[nhz2]

With this PR can_concatenate is now a decoder method instead of a Codec method. I think this makes more sense as different decoders may want to handle concatenated compressed data differently, independently of the Codec.

Pull Request Overview

This PR moves the can_concatenate method from being a Codec method to being a decoder (DecodeOptions) method, allowing different decoders to handle concatenated compressed data differently regardless of the codec used.

• Moved can_concatenate from Codec implementations to their corresponding DecodeOptions implementations
• Updated all references to call can_concatenate on decoder options instead of codecs
• Added backward compatibility by making can_concatenate(c::Codec) delegate to can_concatenate(decode_options(c))
