[luci/pass] Check StridedSlice shape inference

[seanshpark]

StridedSlice shape inference looks incorrect

Source onnx	circle	after circle2circle

output of StridedSlice becomes 1x128x132x128

[seanshpark]

end input of circle model has

tensor: int32[4]
identifier: 183
[
    1,
    128,
    132,
    128
]

which looks strange ...

--> need to check onnx2circle tool.

[seanshpark]

why look at onnx2circle ?

• our target model fails to compile with onnx-tf
• one-import-onnx calls fallback one-import-onnx-ext, which invokes onnx2circle tool

[shs-park]

The onnx2circle tool will be modified by tomorrow nightly release.
Let's check this out then.

Fixed !
