To allow more detailed testing seperating these tests to align with the class hierarchy
This allows for gathering the field (needed for modulus match for the curve) and other curve parameters that could be set on a new group but not read.

I've also added a comment about the design at #425 (comment).
Document the fallback of `field_type` Proper newlines Split declare initialize for C conformance Remove unneeded returns for `rb_raise`

Variable declarations need to be at the beginning of the block while we support Ruby <= 2.6.

This is a basic read API for getting the EC params for a given explicit or named group instance.
