dev: add testing script

This script is posted for discussion.

This script could be used for testing. The script

• Reports on current environment information (eg node --version, whether mongod --version says Illegal instruction, whether the machine supports AVX)
• Cleans up files that might cause build problems.
• Updates dependencies (eg npm ci ).
• Seeks to switch to a branch that is up to date with upstream.
• Run SF.
• Output is logged to a file that can be shared for analysis.
• A --repair mode includes more aggressive cleaning and dependency installation, such as running ansible.

I originally selected Deno rather than bash with the intent of this script being able to run on multiple platforms. After implementing the various features, it is certainly right now targeting the testing platform, and would need work to make it actually multiplatform.
