This PR renames "encoding" to "codec" in the compression package to remove the cognitive dissonance. It also removes the `Enc` prefix for codec identifiers, so that they adhere Go's best practice of naming conventions, e.g. `compression.EncGZIP` becomes `compression.GZIP` when used in a different package.
