After discussing this internally - new methods should be added to the FireblocksSDK class and not in a new one. We should keep the current approach of not introducing new namespaces (NCW is exceptional). Please align this accordingly

@YoavBZ Can you share the reasoning behind it? fireblocks-sdk.ts is already 2000 lines long, and nameSpaces help us prevent name collisions. For example I prefer to keep our methods name simple as sdk.staking.getChains or sdk.staking.approveProviderTermsOfService if we would be force to flatten all under the general sdk, it would have to be called sdk.getStakingChains or sdk.approveStakingProviderTermsOfService.

@YoavBZ We are trying to be similar as possible to they way the auto generated SDK will create our API (from we understand it will be under a separate namespace). As this is a new API and we want to make sure the migration from this SDK to new one will be streamlined as much as possible for clients.
