remove dependency of awos-js in final bundle

its quite big 45m+

currently, both fc invoker and receiver uses awos-js to upload and download params/response

An alternative way shall be create a signatureUrl from the invoker, pass this url to receiver.
If the result is big enough to upload to oss, put it to this url using node http or axios

It opens the possibility of using fc-toolkit as a global command line tool, without installing the full package inside the to be uploaded bundle.

I shall deal with it later with a pr
