Move to micromatch@4 or picomatch

[mrmlnc]

We have a big problem related to package require time (#92). This issue is related to micromatch, which has a very large number of dependencies.

About micromatch@4:

• v4.0 micromatch/micromatch#137

Also micromatch/picomatch has a problem:

• Inaccurate comparison within a regular expression micromatch/micromatch#140
• Difference behavior for dot files on windows and linux #159
• Difference behavior for ( and ) on windows and linux #160

@mrmlnc fwiw I just pushed up picomatch v2.0: https://github.com/micromatch/picomatch/tree/dev. I also got it completely ported to micromatch, and I'm now working on docs.
