resolves #118

This allows schemas that may have custom formats to be used.

As part of this change I've disabled warning log messages as when setting
`unknownFormats: "ignore"` warning messages are emitted everytime a schema
with unknown formats is compiled.

I have not disabled standard or error log messages.

It allows covering opaque types.

I am using this together with a GraphQL endpoint which has custom scalars. These scalars are opaque from the type system so a JSON schema cannot be derived.

* Fix object and null possible type handling.

Remove ajv for multiple type handling.

* Remove object spreading.

* Fixes #101

* Updated test

* Removed slow down
