Bundle commons-codec with common.eval to complete commons-csv's closure

The commons-io fix in v5.6.0 (#65) got the bundled commons-csv past its first
missing transitive dependency, but commons-csv 1.12.0's runtime closure is
both commons-io and commons-codec: it references
org.apache.commons.codec.binary.Base64OutputStream, yielding a second
NoClassDefFoundError under strict OSGi classloading in a materialized product.

commons-csv's own OSGi manifest enumerates its complete runtime closure via
Import-Package: exactly org.apache.commons.codec.binary and the
org.apache.commons.io.* packages. So the closure is bounded (io plus codec),
not open-ended. Bundle commons-codec 1.17.1 the same way commons-io and
commons-csv are bundled: self-contained, private to this bundle's classloader
(not exported), so common.eval carries its entire commons-csv closure inside
its own classloader regardless of what else the product assembles.

Maintenance note: on each future commons-csv upgrade, re-check the csv jar's
manifest Import-Package and bundle any newly added transitive dependency.
