[codec] Hex encode

[Or Mark <or...@gmail.com>]

Hello,

About commons-codec Hex encoding methods,
I suggest adding to Hex static encode method which returns byte[]
It will be consistent with other encoding classes that have such method as
Base64(same package) and MessageDigest.

I don't see a real reason to use instance method in this case.

I would like to contribute this method to library.

Base64 has a static method, but this actually calls a method on a
cached instance using UTF-8.
The use of UTF-8 is noted in the Javadoc.

It uses the instance Charset, as noted in the Javadoc.

What is the use case for this?
