Release v2.2.0: improve collections processing

What's Changed

• GH-180: made it possible to supply collections w/o auto flat-mapping by @sskorol in #175. Note that these changes might be breaking in case if you use Map for linear flat-mapping. Since this release, Map is flat-mapped to Entry. Apart from that, if you use collections with transpose flag, you have to explicitly set flatMap to make auto-expansion. Otherwise, a test will expect collection as is.
• Updated outdated deps and templates by @sskorol in #175
