honor yarn save-exact setting

[dylang]

We use renovate to keep our dependencies up-to-date, and it recommends not including ^ or ~ in the semver version in package.json files so that it can test all version upgrades before merging them.

yarn has a setting for this:

save-exact true

It would be helpful if typesync honored that config.

There might be a similar setting for npm.

Currently typesync always adds the latest version of typings, but maybe it should look for a version that matches the semver of the package and write it out in the same format. That's more work though, and not sure if it's that valuable. If yarn upgrade-interactive still lists updates for packages with no prefixed version, I would not be opposed to making typesync write the exact version always.

That sounds like an even better idea, good thinking!

[jeffijoe]

I always use prefixes so I don't know how yarn upgrade-interactive works in that case. Could you verify this for me please?

Implemented as of v0.4.0.

Amazing job, works great!
