I added yargs types as dev dependency to the package as I want to avoid having this as a dependency but this might lead to the case where yargs types result in any if the consuming project does not install them.
e.g. something like this would not throw an type error
registerCommandToYargs({}, { command: "", describe: "" });but if you install @types/yargs as dependency in that project it will complain that first param is not correct
Argument of type '{}' is not assignable to parameter of type 'Argv<{}>'.
Type '{}' is missing the following properties from type 'Argv<{}>': alias, argv, array, boolean, and 66 more.ts(2345Since this is just an edge use case and all our packages have the types installed, I opted for not adding types as a dependency.

It's find to add types as dev dependency. If we are reexporting the types from this package then we may try duplicating those for now in our source.

I don't think duplicating types for this use case makes sense, and consumers can always install the types if they want to.

The @lodestar/utils package is integral to be used in lightclient and prover. So would be nice if it remains browser compatible and adding yargs and CLI utils may break the bundlers.
We should try to export Node.js specific utils from a different names export and avoid from default export. May be @lodestar/utils/cli could be an option.

These are just types, and a utils function which takes in yargs as an argument. I don't see a reason why we would have to export this separately

I do agree that this is something we should consider, we already use this pattern in the api package.
But for the changes in this PR it is not relevant as it only adds shared types, there is no risk of breaking browser compatibility

demandOption: true already ensures that a file arg is provided

Motivation
Noticed we copy-pasted command types/utils in different packages but we only really maintain the ones in the CLI package.
This PR aims to consolidate types by moving those into the utils package to improve consistency and reduce future maintenance.
Description
@lodestar/utilspackagedemandOption: true) if arg must be provided instead of checking separately
