Migrate base92 package to external repository and update dependencies

This commit updates the project to use an external base92 package from github.com/presbrey/pkg, removing the local implementation. Key changes include:

1. Updated import paths for base92 package across multiple files
2. Replaced local base92 encoding methods with new package functions
3. Updated go.mod to include the new external package dependency
4. Upgraded Go version and dependency versions
5. Simplified base92 encoding and decoding calls in main and test files

The migration ensures minimal code changes while leveraging an externalized base92 implementation. Dependency management and import paths have been carefully updated to maintain project compatibility.
