Avoid bugs when using snakemake's internal API

[itutu-tienday]

Problem

It has been confirmed that when snakemake's internal API (snakemake.Workflow, etc.) is used directly, it affects the operation of a running snakemake process (such as forcing it to stop).

Solution

I decided not to use snakemake's internal API directly, and instead created new code (SmkInternalUtils) based on snakemake's original code.

Testcase

1. The presence or absence of conda env is accurately indicated by an icon in "maintenance/setup_conda_{algoname}" in the Algorithm Tree in the side menu of the Workflow screen.
2. Even if you repeatedly click "Refresh Node" in the side menu while a workflow is running, the workflow will finish normally without affecting the workflow.
