Condition types. A Condition defines which field value of the `Asset` is compared against a given value.
We currently support 4 different kinds of Conditions on `Assets`:
- **TAG**: Refers to a tag of the `Asset`.
- **METADATA_VALUE**: Refers to a value of a custom `MetadataField` of an `Asset`.
- **CUSTOM_METADATA_VALUE**: Refers to a value of a `CustomMetadata` of an `Asset`.
- **EXTERNAL_ID**: Refers to the `externalId` assigned to the `Asset`.
- **FILE_EXTENSION**: Refers to the file extension of an `Asset`.
