Maximum call stack size exceeded with filters

[mrmlnc]

Hello,

And it's me again :)

We have a small problem. When working with large nested directory, we often apply the filter. For example, built-in filter by patterns:

const re = require('readdir-enhanced');

let files = null;

try {
    files = re.sync('./node_modules', {
        deep: true,
        filter: '**/test-*'
    });
} catch (error) {
    console.log('MEMORY: ' + (process.memoryUsage().heapUsed / 1e6) + ' MB');

    console.dir(error, { colors: true });
}

console.dir(files, { colors: true });

In the example above, I call the reading of the directory that contains 20320 entries:

$ npm i jest ava babel-core standard eslint typescript tslint monaco xterm readdir-enhanced

After running the script we get the following:

MEMORY: 9.37484 MB

node_modules/readdir-enhanced/lib/call.js:51
      throw err;
      ^

RangeError: Maximum call stack size exceeded

If I remove any filter (pattern, function), everything works fine.

I don't know how to fix this problem, except switch to use iteration solution instead of recursive solution.

Temporary, I switch to monkey_fix branch in my package.
