fixes #170

Will this be merged? There are many issues regarding pointer analysis.

Since golang.org/x/tools/go/pointer has been deprecated, we should either remove it (as it is in this PR), or at least change the default analysis.

The main changes to the code are:

1. Removed the code related to "golang.org/x/tools/go/pointer" and its associated code, as it caused numerous issues.
2. Added the -algo parameter.
3. Upgraded the Go version to 1.22.
