Struct ItemIdCodec 

pub struct ItemIdCodec;

Dictionary-encoded item IDs with RLE-encoded u32 indices.

Similar to InternedStringCodec but uses u32 indices to support repositories with more than 65535 unique item IDs.

Layout:

[dict_count: u32 LE]
[len_0: u16 LE] [bytes_0...]
...
[run_count: u32 LE]
[run_len_0: u16 LE] [index_0: u32 LE]
...
