feat!: Switch stream implementation to streamx

[sttk]

This PR inherits #322 and updates this repository more for the following points:

1. Upgrades dependencies and drops node <10.13 support

   • rimraf's version is 3, not latest, because the latest version 4 supports only node>=14.
   • eslint, expect, and mocha upgrades to the last versions which supports node v10.
   • Other dependencies upgrades latest versions.

2. Drops through2 and makes use of streamx

3. Drops mississippi and readable-stream

4. Drops remove-bom-buffer, but is-utf8 is used.

5. Skips 2 test cases about directory symlink on Node.js v10 and Windows

   Because EPERM error occurs only on this environment.

In addition, I tryed to drop pumpify by using streamx, etc. in .dest() and .symlink() but cloudn't do them.

NOTE: This package depends on glob-stream which will be bumped up.

Thanks for updating this. I've made some comments, but they are mostly for me to remember what needs to be done to finish up this PR
