opt gives appropriate warning with deprecated optimisers in TFP

This optimiser is deprecated and will be removed in greta "0.6.0".
Please use a different optimiser.

opt converges with TFP optimisers

Code
  o <- opt(m, optimiser = bfgs(), max_iterations = 500)

Code
  o <- opt(m, optimiser = nelder_mead(), max_iterations = 500)

TF opt with gradient_descent fails with bad initial values

Code
  o <- opt(m, hessian = TRUE, optimiser = gradient_descent())
Condition
  Error in `self$run_minimiser()`:
  ! Detected numerical overflow during optimisation
  Please try one of the following:
  i Using different initial values
  i Using another optimiser. (E.g., instead of `gradient_descent()`, try `adam()`)
