[894] Optimize arcpy scripts

ref: Parallel Processing Factor (Environment setting)

ref: Write geoprocessing output to memory

---

• Parallel processing
  • arcpy.env.parallelProcessingFactor = 24
• Write geoprocessing output to memory
  • To write to the memory workspace, specify an output dataset path beginning with memory\ and with no file extension—for example, memory\tempOutput.
  • This strategy improve the model a lot. From 70mins to 5mins.

  • arcpy.analysis.Clip(in_features=PFAS, clip_features=sitebuffer_3_, out_feature_class="memory\\Map3_3a_PFAS_Clip2000m")
