derive(Zeroable) on fieldful enums and repr(C) enums (#257) 
* Add support for deriving Zeroable for fieldful enums if:

1. the enum is repr(Int), repr(C), or repr(C, Int),
2. the enum has a variant with discriminant 0,
3. and all fields of the variant with discriminant 0 are Zeroable.

* Allow using derive(Zeroable) with explicit bounds. Update documentation and doctests.

* doc update

* doc update

* remove unused

* Factor out get_zero_variant helper function.

* Use i128 to track disciminants instead of i64.

* Add doc-comment for `get_fields`

bytemuck_derive

Derive macros for bytemuck traits.

MSRV: None!

This is an opt-in bonus feature for bytemuck that doesn't particularly do anything you couldn't do yourself, and so MSRV is not a strong consideration for this crate.
