Feat/argent features

[Th0rgal]

This pull request was requested by Argent as part of their initiative to distribute argent.stark subdomains via a smartcontract using our native resolver. It introduces a revoke_domain function which can be used by the controller of a domain (i.e. its direct owner or the owner of one of its parents) to reset the specified domain and its subdomains recursively. This comes with a test ensuring the controller's domain is not reset and reset works fine for the specified subdomains and its own recursive subdomains. It doesn't test for assert_control_domain feature as it is already tested separately.

It also introduces a fix for a small bug found by Leo from Argent where following these steps:

1. Register subdomain (call transfer_domain)
2. Set main id
3. Call transfer_domain again (on the same subdomain)
4. Call address_to_domain
   Would result in a panic instead of resolving to 0 (panic should happen only when cairo introduces try/catch).
