Pull Request Overview

This PR implements a new SVM client along with several supporting refactors and improvements to address parsing and event handling across the codebase. Key changes include:

• Enhancements to AddressUtils to support both base16 and base58 encoded addresses for EVM and SVM.
• Addition of the SVM Spoke Pool client and associated event processing logic.
• Removal of deprecated SVM helper files and reorganization of the SVM-related modules.

Pull Request Overview

This PR introduces support for an SVM-based SpokePoolClient as part of the epic “feat(epic): add SVM client” while standardizing terminology by renaming block‐related configuration fields (e.g. fromBlock, latestBlockSearched) to height‐based equivalents (e.g. from, latestHeightSearched). Key changes include new file additions for the SVM client, updates to client base classes and helper functions to consistently use the new naming, and necessary adaptations in the EVM-specific client implementations and related utilities.

src/clients/BundleDataClient/BundleDataClient.ts	Extended support to SVM clients by branching based on client type and calling the corresponding fill event lookup utility.
src/clients/BaseAbstractClient.ts & Others	Widely replaced “Block” terminology with “Height” to reflect updated event search config.
Various SVM and EVM utility files	Updated to follow new naming patterns and support the multi-chain approach with SVM support.

• [nitpick] Ensure that the naming 'SvmSpokePoolClient' is consistently used across the codebase, paying special attention to case sensitivity given the difference between 'Svm' and 'SVM' in related identifiers.

import { SvmSpokePoolClient } from "./SVMSpokePoolClient";

src/clients/BaseAbstractClient.ts:22

• [nitpick] Ensure that renaming properties from 'firstBlockToSearch' to 'firstHeightToSearch' (and similarly 'latestBlockSearched' to 'latestHeightSearched') is consistently updated across all documentation, tests, and references to avoid potential confusion.

public firstHeightToSearch = 0;

I think this looks good!
