Inaccurate association of file extension .pb to "PureBasic" instead of "protobuf"

There are many examples on github.com, e.g. “PureBasic” in ONNX

Since now .pb is more likely to be a protobuf binary instead of Basic codes, it should either label .pb file as ‘protobuf’ or skip labelling if the file is actually binary.
