Hi,

I am prototyping a dataflow job that reads from GPG encrypted files. I got this working, but had to jump through some hoops to supply a new "compression" format to TextIO: I basically had to copy a good part of TextIO.Read only to add a {{public Read withDecompressingChannelFactory(DecompressingChannelFactory decompressingChannelFactory)}} method similar to {{public TypedWrite<UserT, DestinationT> withWritableByteChannelFactory(WritableByteChannelFactory writableByteChannelFactory)}} in TextIO.Write.

Would it be possible to add a method {{withDecompressingChannelFactory}} or {{withReadableByteChannelFactory}} to TextIO.Read to allow users to plug in custom decompression/decryption code?
