Update normalization to handle the new $ref data types (including binary data)

[edgao]

https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/bases/base-normalization/normalization/transform_catalog/utils.py needs to be updated to check for $ref values instead of type/airbyte_type/format. This updated version of normalization will never see old-style catalogs, because it will be released after the platform protocol versioning migrations, and normalization is released as part of platform (i.e. it's impossible for someone to upgrade normalization without also upgrading platform).

Also, add handling for oneOf declarations (which will replace type: [...] decls).

Normalization also should add handling for BinaryData. A minimal implementation is to just treat this as string; a less-minimal implementation is to use destination-specific BINARY columns.
