This would be nice. We could just test each variant as uN against the input, so it should be trivial to autogenerate.

on the other hand i had wanted to do the bitfield crate without any proc macros (mostly for masochism-related reasons)...

feat(bitfield): add enum_from_bits! macro
8ef82d3 
This branch adds a macro to the `mycelium-bitfield` crate that allows
automatically generating `FromBits` implementations for `enum` types
that are `repr(u{N})`. For example, we can now write:

```rust
mycelium_bitfield::enum_from_bits! {
    #[derive(Debug, Eq, PartialEq)]
    pub enum MyGeneratedEnum<u8> {
        /// Isn't this cool?
        Wow = 0b1001,
        /// It sure is! :D
        Whoa = 0b0110,
    }
}
```

This probably _should_ be a `derive` proc-macro but I'm having so much
fun doing `macro_rules!` crimes in the bitfield crate for whatever
reason...

Closes #443
