Feature request: Haskell module namespace for compiled Proto files

[unclechu]

Take for instance test files from test-files/ directory, if you compile them you get these Haskell modules:

• TestProto
• TestProtoImport
• TestProtoLeadingDot
• TestProtoNestedMessage
• TestProtoOneof
• TestProtoOneofImport
• TestProtoProtocPlugin

This pollutes top-level module namespace. It would be nice to provide an argument to put the generated Haskell file under some namespace. Sometime like this:

compile-proto-file --moduleNamespace 'Data.Proto.Model'

And then all the modules would be named like this:

• Data.Proto.Model.TestProto
• Data.Proto.Model.TestProtoImport
• Data.Proto.Model.TestProtoLeadingDot
• Data.Proto.Model.TestProtoNestedMessage
• Data.Proto.Model.TestProtoOneof
• Data.Proto.Model.TestProtoOneofImport
• Data.Proto.Model.TestProtoProtocPlugin

And this would change only Haskell module names and nothing else.

P.S. I’ve tried to implement myself but I couldn’t come up with a good solution yet. I need to get deeper into the code. Maybe you have some ideas of how this can be done?
