SuperTable fields don't get filled in under certain conditions.

[anvart]

Description

I've got a section with SuperTalbe field which has all kind of (text, lightswitches, datetime, entry) non-mandatory sub-fields. This condition (took me some time to spot):

feed-me/src/fields/SuperTable.php

Line 151 in 1d774e0

if ((is_string($value) && !empty($value)) || (is_array($value) && !empty(array_filter($value)))) {

ignores things like Carbon\Carbon So if there are only Date fields in a ST row, it won't get filled in.

Steps to reproduce

1. Create a section with a SuperTable field which would only contain DateTime sub field(s)
2. FeedMe it with anything
3. Get no rows
