Add use_version() and use_github_action(), bump to 0.2.0 (#3)

* Reformat R/dev.R and R/release.R via rformat

* Add create_package() and bump to 0.2.0

New create_package() scaffolds a tinyverse-flavored R package:
DESCRIPTION with Authors@R (optional ORCID), NAMESPACE, .Rbuildignore,
NEWS.md, tests/tinytest.R entry point, and an optional starter hello()
function with matching tinytest test. Pure base R, no new Imports.

* Add use_version() to bump DESCRIPTION + NEWS.md

* Add use_github_action() to write r-ci workflow

* Drop create_package() and switch dev versioning

- Remove create_package() in favor of pkgKitten::kitten().
- Fix bump_version("dev"): increment a 4th digit starting at 1 instead
  of using the .9000 convention.
- Rewrite test_use_version and test_use_github_action to use inline
  minimal package scaffolds.

* Refactor load_all() to not modify the search path

load_all() now returns the populated environment and takes an optional
env arg so callers can supply their own target. It no longer calls
attach(), so tinypkgr's source is free of search-path side effects and
R CMD check --as-cran is clean (0/0/0 aside from the new-submission
NOTE).

Users who want the previous auto-attach behavior can do it themselves:

  attach(tinypkgr::load_all(), name = "tinypkgr:mypkg")
