Create go package

Issue To Be Solved

Downstream tooling dependencies (such as onflow/flow-emulator) will need to ingest contract templates from a go package & release. Once bridge contracts are finalized and the standup script is updated, they will need to be released as a go package so bridge functionality can be included in emulator and Flow CLI.

Definition of Done

• Create contracts and transaction templates package that includes standup script
• Test package to make sure it returns correct code

@sisyphusSmiling Doesn't the go package that is in the repo already work for this? Couldn't we just import that and run main.go to set up on the bridge in flow-emulator?

@joshuahannan potentially, but it needs updating in both content and likely the SDK used. I could see the use of Overflow potentially leading to circular dependency issues. Created #147 to track.
