Does not work with term meta + split_values

[jazbek]

The plugin works great with CMB2 boxes on posts (need to use PR #45 + an api key), but it does not work with CMB2 boxes on terms. The value does not save.

The map also loads very narrow:

EDIT: Turns out, it's setting split_terms to true that's not updating the split values. It works fine when split_values is false.

Thanks for debugging this further @jazbek.

I'll take a look how CMB2 is handling this internally. Might just be a case of using update_term_meta if we're in a term context.
