add -json flag for json output

[collinforsyth]

This is a great tool for helping manage developer environments. One thing that would increase the usability for our team is being able to check the binaries from list and ensure that they are installed from a script.

Rather than having to parse the tab output with bash, I think a json output makes this much easier. My proposal is to add a -json flag for output.

Usage

❯ ./bingo list -json
[
        {
                "name": "copyright",
                "binary_name": "copyright-v0.0.0-20210112004814-138d5e5695fe",
                "package_version": "github.com/efficientgo/tools/copyright@v0.0.0-20210112004814-138d5e5695fe",
                "build_env_vars": null,
                "build_flags": null
        },
        {
                "name": "embedmd",
                "binary_name": "embedmd-v1.0.0",
                "package_version": "github.com/campoy/embedmd@v1.0.0",
                "build_env_vars": null,
                "build_flags": null
        },
        {
                "name": "faillint",
                "binary_name": "faillint-v1.8.0",
                "package_version": "github.com/fatih/faillint@v1.8.0",
                "build_env_vars": null,
                "build_flags": null
        },
        {
                "name": "goimports",
                "binary_name": "goimports-v0.0.0-20210112230658-8b4aab62c064",
                "package_version": "golang.org/x/tools/cmd/goimports@v0.0.0-20210112230658-8b4aab62c064",
                "build_env_vars": null,
                "build_flags": null
        },
        {
                "name": "golangci-lint",
                "binary_name": "golangci-lint-v1.50.0",
                "package_version": "github.com/golangci/golangci-lint/cmd/golangci-lint@v1.50.0",
                "build_env_vars": null,
                "build_flags": null
        },
        {
                "name": "mdox",
                "binary_name": "mdox-v0.9.0",
                "package_version": "github.com/bwplotka/mdox@v0.9.0",
                "build_env_vars": null,
                "build_flags": null
        },
        {
                "name": "misspell",
                "binary_name": "misspell-v0.3.4",
                "package_version": "github.com/client9/misspell/cmd/misspell@v0.3.4",
                "build_env_vars": null,
                "build_flags": null
        },
        {
                "name": "proxy",
                "binary_name": "proxy-v0.10.0",
                "package_version": "github.com/gomods/athens/cmd/proxy@v0.10.0",
                "build_env_vars": null,
                "build_flags": null
        }
]

For example, this is a small script that checks if we have a binary installed:

for b in $(./bingo list -json | jq -r '.[] | .binary_name'); do
        if ! command -v $b;
                then echo "$b not found";
        else
                echo "$b found"
        fi
done

Output:

Hopefully not too big of a PR! Let me know if there's anything else needed for this.

I realized I didn't update the Usage functions.

Will get to that on Monday.

Sorry for missing, this is great addition!

I'm afraid we we need to add another commit to get fresh results from CI.

Looks like no interest to pursue this, so closing for now. We can always reopen! Thanks!
