Combine UDFs into appropriate objects

[greebie]

There are a few image udfs that could be combined into a single object rather than having multiple files.

For example, ComputeMD5 and ComputeImageSize might be better in a single object for image / byte array utilities. It would also distinguish ComputerMD5 (takes a byte array) from StringUtils.computeHash() (takes a string).

Suggested groupings could be:

• imageUtils
• String (or text) Utils (detect language, json output etc.)
• Twitter-related Utils (detect @ mentions, hashtags etc.)
• Network graph-related Utils

With activity since April 2018, do we need to revisit this issue? Rewrite it, or close it?

Yeah, and a lot of that activity was @lintool’s major package restructuring. My instinct here is to close but I’d defer to Jimmy.
