[feat] add --only option to cli

[bryanlarsen]

Add --only option to cli, with same behaviour as k6 convert --only

[legander]

Hello @bryanlarsen, thank you for wanting to contribute.
Sorry for taking ages to respond..

We have been discussing this --only option and have concluded that we do want to add support for it but with following requirements:

• The CLI option should be forwarded to src/convert.js and filtering be done as a first step in the covert function instead of in the CLI layer. The reasoning being that any options that can modify the result should be passable programmatically as well to support integration usage and not only CLI.
• Naming of --only is TBD, perhaps --include is better.
• Multiple values should be specified by stacking options rather than being comma separated.

--include test.k6.io,test-api.k6.io
# becomes
--include test.k6.io --include test-api.k6.io

You are most welcome to continue with the implementation, if so please let me know.

Thanks, but we realized that the "right" way to use har-to-k6 is to transform the har file using a jq or javascript script before passing it to har-to-k6 so would no longer need nor dogfood this option.

Ah okey cool! Are you using the programmatic usage then?
Out of curiosity, how are you using har-to-k6 and in what step of the development process? If you even can or want to share that information.
