Snowflake Serializer does not work in both directions

[NyCodeGHG]

When using Snowflakes in a database, for example with kotlinx.serialization and KMongo, you can easily serialize the snowflake and write it to the db. But when you try to read it again, you get an exception because Kord tries to read a long, but it was saved as a String. It would be better when the de/-serialization would be consistent.
