Trait orc_rust::reader::decode::NInt

pub trait NInt: PrimInt + CheckedShl + BitOrAssign + ShlAssign<usize> + Debug + Display + Binary + Send + Sync + 'static {
    type Bytes: AsRef<[u8]> + AsMut<[u8]> + Default + Clone + Copy;

    const BYTE_SIZE: usize;

    // Required methods
    fn from_u64(u: u64) -> Self;
    fn from_u8(u: u8) -> Self;
    fn from_be_bytes(b: Self::Bytes) -> Self;

    // Provided methods
    fn empty_byte_array() -> Self::Bytes { ... }
    fn zigzag_decode(self) -> Self { ... }
    fn decode_signed_from_msb(self, _encoded_byte_size: usize) -> Self { ... }
}

Helps generalise the decoder efforts to be specific to supported integers. (Instead of decoding to u64/i64 for all then downcasting).
