Support custom transformers?

[dsherret]

What are your thoughts on adding the ability for this tool to support custom transformers?

Details:

• The ts.transpileModule function (used here) supports providing custom transformers as an option (see here).
• Build tools like webpack support providing custom transformers as shown here: https://github.com/dsherret/ts-nameof/blob/master/setup/webpack.md
