Reduce dependencies

[ai]

According to why-npm-i-so-long Astroturf 1.0 took 16 MB of node_modules, which is huge for this project.

npm.anvaka.com shows a huge network of dependencies.

I see a few ways to reduce dependencies:

• Replace chalk with colorette. It has 0 sub-dependencies and works faster (we migrate to it in PostCSS).
• Replace comsiconfig to lilconfig. It has the same API but much smaller dependencies (I do the same in Size Limit).
• Do not load the whole lodash and add only subproject (like lodash.uniq) to dependencies
• Review other dependencies and avoid small and simple dependencies with big tree of sub-dependencies
