Feature: Support CompactString

[PlainBane]

Hi,
Could you consider adding support for CompactString as an alternative for String in structs with small string values.
It would add a bit of performance improvement when using structs.

Can you please explain how you plan to use it? I'll see if I can get it implemented.

I use it in Axum http api structs (To optimize small string values). So if I Serialize / Deserialize struct, there are lots of CompactString instead of String. If I then use skytable to cache some of this data, I end up having to convert CompactString -> String and back. I could try to add it myself and do pr.
Thanks.
