lodash-fp support

[megawac]

Discussed this a bit in gitter a bit a while ago. Not sure the best path here, e.g. convert

require('lodash-fp)   ->  require('lodash-fp/convert')('./lib/lodash)

However, this runs into difficulties if the user is using es6 imports.

The easiest solution is to generate a new file for lodash.fp

Should also look in to and see if esperanto can help out on this one
