Pull #603

travis-ci

Change TagContext serialization methods to use byte[] (closes #213).

The signatures changed from

    void serialize(TagContext tags, OutputStream output) throws IOException
    TagContext deserialize(InputStream input) throws IOException

to

    byte[] toByteArray(TagContext tags)
    TagContext fromByteArray(byte[] bytes) throws IOException

fromByteArray can only fail if there is a parse error, so we should probably
change it to use a more appropriate exception type later.

This commit also refactors the toByteArray implementation to remove the
possibility of a checked exception, since it is no longer doing IO.
