This PR adds a type directive for BytesTypeNodes. Here are some examples.

Bytes with no size constraint

pub struct Buffer<'a> {
  pub authority: Pubkey,
  #[codama(type = bytes)]
  pub data: &'a [u8],
}

Bytes with size prefix

pub struct Buffer<'a> {
  pub authority: Pubkey,
  #[codama(type = bytes)]
  #[codama(size_prefix = number(u32))]
  pub data: &'a [u8],
}
