allow for uppercase letters as the output of Hex.encodeHex()
------------------------------------------------------------
Key: CODEC-74
URL: https://issues.apache.org/jira/browse/CODEC-74
Project: Commons Codec
Issue Type: Improvement
Reporter: Dimitar A. Stoikov
Priority: Minor
Perhaps this is recurring. Sorry if this is the case.
As of now, Hex.encodeHex() will only use lowercase letters. There may be
clients of this class who need the output in uppercase. Such clients who want
to use the library, now need to do the upper-casing externally to the class.
Being able to choose the output format will help reducing computing cycles,
which is often an objective for library routines.
