Research direction

Start by reproducing microbundle --format cjs,iife --name mynth_test and inspect how the CJS and IIFE output names are generated. Done means the two formats produce distinct output files and building IIFE no longer overwrites CJS.

Written by the indexing model from the issue text.

Description

When exporting IIFE format, name of the output file is the same as for CJS format so CJS is overwritten
