Get all Term data from database by Term field and data.
Warning: $value is not escaped for 'name' $field. You must do it yourself, if required.
The default $field is 'id', therefore it is possible to also use null for field, but not recommended that you do so.
If $value does not exist, the return value will be false. If $taxonomy exists and $field and $value combinations exist, the Term will be returned.
