migrate to Thoth.Json.Core

[joprice]

I tried out migrating to Thoth.Json.Core and it seems that Auto is the only missing piece master...joprice:thoth-json-codec:thoth-core. I changed things in place, but perhaps the code should just be copy pasted into a new folder named something like thoth-json-core-codec?

Hi there 👋

I have a draft PR for auto support on top of the new Thoth.Json.Core: thoth-org/Thoth.Json#189
That would need to be merged before auto codecs can be implemented for the new Thoth.

My PR moves auto into a new package so that it is possible to use core Thoth without any reflection.

So I think a good approach here would be to have two packages here:

• Thoth.Json.Codec
• Thoth.Json.Auto.Codec

... or something like that.

I think it would also be great to roll this code into the main repo, if possible.
