Minor NEL type fixes (#10860)
* Fix TODO about typing Fix was simple: just request an array2f. * Add type ignore Maxout has a more restrictive type than the residual layer expects (only Floats2d vs any Floats). * Various cleanup This moves a lot of lines around but doesn't change any functionality. Details: 1. use `continue` to reduce indentation 2. move sentence doc building inside conditional since it's otherwise unused 3. reduces some temporary assignments
