[Feature] Bytes data type

[brianferri]

Since https://github.com/prisma/prisma/releases/tag/2.17.0 the Bytes data type has been added to accommodate for byte array/binary data types (https://www.postgresql.org/docs/current/datatype-binary.html#DATATYPE-BINARY) but it is currently not a method on the PrismaModel. The obvious solution is to use the raw method instead, but for coherence's sake and updating the package to Prisma's latest version, I think it'd be a nice addition

Thanks! I can take a look, but a little busy with work at the moment. Anyone else is free to take and any other issue this in the meantime. :)
