Updates for parsnip 1.2.1.9004 and dial 1.3.0

[topepo]

parsnip revdeps gives this error:

## Newly broken

*   checking S3 generic/method consistency ... WARNING

    set_mode:

    set_mode.cluster_spec:

    See section ‘Generic functions and methods’ in the ‘Writing R
    Extensions’ manual.

There are snapshot updates from dev hardhat and changed the use of Latin hypercube designs to the newish grid_space_filling() to avoid a warning.
