Restrict the type of values that can be posted

[prabhu]

The idea is to cut down on injection possibilities.

curl -X POST http://localhost:9090/sbom \
        -H 'Content-Type: application/json' \
        -d '{
      "url": "https://github.com/HooliCorp/vulnerable-aws-koa-app.git",
      "type": { "foo": "bar" },
      "multiProject": "true"
    }'
{"error":"TypeError: Invalid value type: object.","details":"Options can only be of string, number, and array type. No object values are allowed."}

@bandhan-majumder can you test this and make sure we have not broken any legitimate functionality?

I tested with all the possible options, it's working fine.
