Minor typos

[CGMossa]

Thanks for accepting my previous issue. I'm exploring odin. I find it very lovely.

Found more typos. This time a PR is submitted instead.

I'd like to also hijack this PR and ask about this:

odin::odin({
  update(S) <- -beta * S * I
  update(I) <- +beta * S * I
  N <- S + I

  beta <- user(0.005)
  initial(S) <- 100.0
  initial(I) <- 1.0
}, verbose = TRUE, validate = TRUE, target = "c", pretty = TRUE,
  skip_cache = TRUE) ->
  model_generator
model_generator$new() -> model
model$run(seq.default(0, 5, length.out = 25))

Error: Expected integer input for 'step'
Called from: as_integer(step)

Why is that? Passing numeric steps for the lorenz example works.

> traceback()
4: stop(sprintf("Expected integer input for '%s'", name), call. = FALSE)
3: as_integer(step)
2: private$odin$wrapper_run_discrete(self, private, step, y, ..., 
       use_names = use_names) at odin.R#100
1: model$run(seq.default(0, 5, length.out = 25))

Somehow it works when I correct the albeit stupid mistake deriv instead of update.. But I guess that makes total sense.

Perfect! This works and may get reviewed now.
