Expose idb AUTH_DB_NAME and OBJECT_STORE_NAME constants

[peterpeterparker]

Feature request

It would be cool if both constants AUTH_DB_NAME and OBJECT_STORE_NAME from auth-client db.ts would be exposed for the consumer of the lib.

This is particularly interesting - for maintainability reason - for those who want to read the delegation and identity information that are saved in indexeddb.

Can do! For fun, you can also just construct the IdbStorage interface with default options and get and set those values freely

[peterpeterparker]

@krpeacock that's an excellent idea! I will try tomorrow, if it works it's way better than exposing the constant.

@krpeacock indeed using IdbStorage in our web worker would work and therefore make this feature request unuseful.

Being said, while replacing our custom code in web worker with agent-js and this class, I noticed the two following issues for which I provided PRs:

• fix: auth-client usage in web worker and nodejs #611
• fix: logout clear storage missing promise await #612

Let me know if these make sense to you too. Once merged, it would be cool if you could release a new version because we will need such improvements to integrate the last version of agent-js in NNS-dapp PR #1247.
