[WASM] The tfjs-backend-wasm module try to find simd binary when I specify a wasm file

Describe the problem or feature request

I use setWasmPath to set path to wasm binary(tfjs-backend-wasm.wasm), but the module seem to find tfjs-backend-wasm-simd.wasm in the same path instead and cause the error file not found. Why the module try to import simd binary file since I specified a wasm file?

Hi @akineeic - thank you for reporting this. This behavior will be fixed in our next release: #3627

Our next release will deprecate setWasmPath and include a new function setWasmPaths (notice the 's' at the end) which will accept either a string indicating the folder where all your WASM binaries can be found, or a map specifying the location of each binary: https://github.com/tensorflow/tfjs/blob/master/tfjs-backend-wasm/src/backend_wasm.ts#L403
