Use Own Base58

• If this is a code change: I have written unit tests.
• If this changes code in a published package: I have run pnpm changeset to create a changeset JSON document appropriate for this change.
• If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.

Motivation

I have been getting annoyed by this package resolution warning:

warning near-api-js > @near-js/utils > bs58 > base-x@2.0.6: use 3.0.0 instead, safe-buffer has been merged and release for compatability

This is caused by a very tiny piece of middleware (bs58) that is not very professionally managed or updated and prevents us from keeping the primary dependency updated.

To solve this, we copy the 3 lines of code coming from that middle ware into an identical file directly into this project and migrate our dependency to base-x.

Alternative solution would be to fix the dependency's build issue and re-depend on it.

Test Plan

Added unit tests transcribed from the former dependency.
