Use "Py2CpgOnFileSystem() to create Cpg (config=config). get" for missing nodes

[Coker-Cooler]

`val config = io.joern.pysrc2cpg.Py2CpgOnFileSystemConfig()
config.inputPath = "./sast-benchmark-master-python-flask"
config.outputPath = "./cpg.bin.zip"

val cpg = Py2CpgOnFileSystem().createCpg(config = config).get
try {
  val context = new LayerCreatorContext(cpg)
  new Base().run(context)
  new TypeRelations().run(context)
  new ControlFlow().run(context)
  new CallGraph().run(context)
  val options = new OssDataFlowOptions()
  new OssDataFlow(options).run(context)
  codePropertyGraph = cpg
} catch {
  case e: Exception =>
    throw e
}
cpg.close()`

The cpg created using the above code may have missing nodes compared to the cpg nodes loaded by joern-cli's importCpg function, specifically some nodes that are dependent on third-party components. Am I missing some SDKs loaded on other edges or nodes？
