Add transformation and composition operators to JsonCodec

[jdegoes]

Just as JsonEncoder and JsonDecoder support a wide range of operators, which transform and combine codecs, so also can JsonCodec support operators, including:

• orElse
• orElseEither
• zip
• zipLeft
• zipRight

These will have type signatures similar to the existing type signatures.

In addition, an xmapOrFail could be added, probably here and to the parent types.

@afsalthaj of course

[jdegoes]

No one is working on this, I don't think.

@fsvehla The specific methods mentioned seem to be taken care of in zio2 , is there anything left to be done for this issue? edit: I see xmapOrFail is not done yet
