tfjs 2.8.0 is broken and introduces regressions in tf.image.cropAndResize

As subject line says, TFJS 2.8.0 unfortunately seems like a broken version.

First, default parameter in cropAndResize was unintentionally removed (and apparently just re-added via #4407) which causes quite a lot of errors in existing apps

Second, even when specifying resize method as bilinear, cropAndResize FAILS on WebGL baclend:

Uncaught (in promise) Error: Failed to compile fragment shader.
    at createFragmentShader (webgl_util.ts:103)
    at GPGPUContext.createProgram (gpgpu_context.ts:280)
    at compileProgram (gpgpu_math.ts:93)
    at backend_webgl.ts:858
    at MathBackendWebGL.getAndSaveBinary (backend_webgl.ts:902)
    at MathBackendWebGL.runWebGLProgram (backend_webgl.ts:857)
    at Object.cropAndResize3 [as kernelFunc] (CropAndResize.ts:35)
    at kernelFunc3 (engine.ts:590)
    at engine.ts:660
    at Engine.scopedRun (engine.ts:453)

With WebGL code dump highlighting error in

204 setOutput(float(undefined));

IMO, this is is blocking bug - once fixed, TFJS packages should be republished! (and I’m not sure how this passed any level of testing?)

Btw, same code confirmed working after downgrade to tfjs 2.7.0.

Hi @vladmandic, we are going to release the fix in 2.8.1 very soon.

tfjs 2.8.1 fixes this issue, but exposes another issue in #4429
