[RFC] Implement Except Set Operation

A first-time contributor here! I would love to open up a pull request and implement some stuff! Looks like the except function might be the lowest hanging fruit, so I’d love to take a stab at it.

On the lodash documentation page, the without function uses a signature like this:

const items = _.without(array, ...items);

How about something like this?

const squares = from([1, 2, 3])
  .except(2) // or maybe name it `without` instead?
  .map(e => e * e)
  .toArray();

probably would be more flexible as a function, and more uniform with the rest of the lib.

.not(e => e == 2)

EDIT: eh, i guess my version is just the inverse of filter. i’d still prefer to keep the minimal api:

.filter(e => e !== 2)
