Make it possible to override codecs for primitive types

[grouzen]

It could be solved by https://github.com/zio/zio-schema/blob/7610e6085046c4ab3c6711b4d63390e60a062995/zio-schema-derivation/shared/src/main/scala/zio/schema/Deriver.scala

Get some inspiration by looking at https://github.com/grouzen/zio-apache-parquet:

The PoC for this approach was done in another library I'm working on: https://github.com/grouzen/zio-apache-parquet
