feat: Adding support for benchmark init command

[hassila]

Description

Fixes #129

Adds swift package benchmark init <target> supporting creation of boilerplate + adding target to Package.swift.

How Has This Been Tested?

Manual testing.

Minimal checklist:

• [x] I have performed a self-review of my own code
• [x] I have added DocC code-level documentation for any public interfaces exported by the package
• [ ] I have added unit and/or integration tests that prove my fix is effective or that my feature works
