Compression about blockexchange HOT 2 CLOSED

Thanks for the kind words 👍

Compression is currently only applied on the database level (https://github.com/blockexchange/blockexchange_server/blob/9f0af3fdb49d89a01a11f2585406c5faaf7fe136/src/util/serializer.js#L64-L67).
There is no compression for the in-flight map-data yet, it is transferred as plain json-data (it may be compressed with gzip if the client can handle that, haven't tested that yet)

In the future, if there is significant benefit in another compression-strategy, it could be added with different version-headers, i don't see a problem with retrofitting that later 😏

closing this, i rewrote the server-part from nodejs to go and also changed the serialization-format and compression:

The data and metadata is now compressed with deflate (both the server and the mod can use this) so the most cpu-intensive operation can be done on the client/mod side, the server now only needs this for the preview, all other things are basically just pass-through.
In-flight requests encode the binary data now with base64

About the size-issues: i don't have worries about that yet, also: air-only blocks are handled now properly :)

Feel free to comment/reopen if you have ideas or issues 👍
