strum breaking changes

The Iterator struct generated by EnumIter now has new bounds on it. This shouldn't break code unless you manually added the implementation in your code.

The `EnumVariantNames` macro has been renamed `VariantNames`. The deprecation warning should steer you in the right direction for fixing the warning.

[#337](https://github.com/Peternator7/strum/pull/337): Fix missing generic impls for `EnumTryAs`

EnumDiscriminant now inherits the repr and discriminant values from your main enum. This makes the discriminant type

The Iterator struct generated by EnumIter now has new bounds on it. This shouldn't break code unless you manually

`Display` now supports format strings using named fields in the enum variant. This should be a no-op for most code.

The `EnumVariantNames` macro has been renamed `VariantNames`. The deprecation warning should steer you in

Reverted [#217](https://github.com/peternator7/strum/pull/217) because it was disruptive and non-trivial to work around

[#224](https://github.com/Peternator7/strum/pull/224) tweaked the algorithm.

`from_repr` will be `const` if you use a recent rust version.

[#185](https://github.com/Peternator7/strum/pull/185) Adds the `FromRepr` derive that adds a `from_repr(x: usize) -> Option<Self>`

This cannot be a trait method currently because only inherent methods support `const`.

[#186](https://github.com/Peternator7/strum/pull/186) Automatically implement `TryFrom<str>` for enums that implement `EnumString`.

This is a small breaking change. If you had manually implemented `TryFrom<str>` for your enum, this will cause a conflict. You

It is unlikely this will break anyone, but the new signature for functions generated by EnumMessage

MSRV is updated to 1.32 because `heck` does not work in `1.31.1` anymore. Rust 1.32 came out Jan 2019 so hopefully
