Preparing Go toolchain OmniBOR Input Manifest generation

Is your feature request related to a problem? Please describe.
We don't yet know the best way to set up a repo that modifies the Go toolchain code for adding use of this module. We need this repo to be as well formatted as possible so that it is most likely to be accepted by the go developers.

Describe the solution you'd like
We should look at the CONTRIBUTIONS.md and other contribution guidelines for the golang/go repo for how to set up a repo that has a new go toolchain feature. Ideally, we should look for how previous features have made it into the toolchain, like previous goexperiments.

Additional context
Here is the Golang repo that we would be adding new features to. We will need to set up a new fork of the repo to add our changes to the toolchain.

Definition of Done

• Set up new fork for modifying the toolchain
• Read into contribution guidelines for making changes to the toolchain
• Make some initial changes using the guidelines
• adjust issue templates with the development procedure for contributers
