feat: introducing hub, our new wallet management

[yeager-eren]

Summary

Adding Hub into our wallets-core.

We've experimented with hub in the original PR and I applied comments as well. In this PR, we will add Hub and its functionality first then in a separate PR we will have an adapter to let us use Hub and legacy system alongside each other.

I tried to have more test coverage and also code documentation in this PR in compare to original PR. I also cleaned up namespace and provider code to have more code quality. One notable change is I renamed and to and_then and also or to or_else to communicate the intention better. Previously, We called and, or, before, after hook actions, but I made into two separate thing, and_then and or_else are (logical) Operators and after and before are hooks.

How did you test this change?

If you need documentation on the concepts, it's available on original PR, other than that I tired to document code using JSDOC as well.

You can review this PR using unit and integration tests that it has, and also I suggest to review in this order:

1. hub/namespaces
2. hub/providers
3. hub/hub.ts
4. hub/store
5. /builders
6. /utils

Great job. I just added some minor comments.

LGTM, I've reviewed EVM and some part of core namespace.
