TypeError: async.eachOf is not a function

[viniciusrtf]

Hi folks!

I followed README and typed this:

$ node index.js myfile.json myfile.srt

And got this error:

/home/xyz/dev/tools/aws-transcribe-to-srt/lib/srtConvert.js:31
        async.eachOf(json.results.items, function(item, index) {
              ^

TypeError: async.eachOf is not a function
    at SrtConvert.convertFile (/home/xyz/dev/tools/aws-transcribe-to-srt/lib/srtConvert.js:31:15)
    at fs.readFile (/home/xyz/dev/tools/aws-transcribe-to-srt/index.js:33:40)
    at FSReqWrap.readFileAfterClose [as oncomplete] (internal/fs/read_file_context.js:53:3)

Installed node version:

$ node --version
v10.19.0

Is it a node version issue?
