AI Summary: This GitHub issue proposes removing the `fastexcel-support` module from the `fastexcel` core repository. The motivation is that the `fastexcel` project already depends on an external Maven dependency for `fastexcel-support` version 0.0.1, making the internal module redundant and unnecessary to maintain. The proposed solution is to simply remove the module from the main project starting from the next version.
