Breaking: replace bump with cc add command

Existing behavior remains the same, so `hallmark cc add <target>`
does the same as `hallmark bump <target>` did.

The new command is more generic however: it also supports inserting
a release into the changelog for an existing version (regardless of
whether that version is first, last or somewhere in the middle).

In addition, there's a new option `--no-commits` to skip populating
the release with commits. Effectively only creating a markdown
heading (with a version number, link and date).

Closes #84

+#### `fix`
+
+Fix markdown files in place.
+
+#### `cc add <target>`
+
+Add a release to `CHANGELOG.md` and populate it with commits. The `target` must be one of:
+
+- A release type: `major`, `minor`, `patch`, `premajor`, `preminor`, `prepatch`, `prerelease`
+  - These take the current version from the semver-latest tag, release or `package.json` (whichever is greatest if found) and bump it
+  - The `major` type bumps the major version (for example `2.4.1 => 3.0.0`); `minor` and `patch` work the same way.
+  - The `premajor` type bumps the version up to the next major version and down to a prerelease of that major version; `preminor` and `prepatch` work the same way.
+  - The `prerelease` type works the same as `prepatch` if the current version is a non-prerelease. If the current is already a prerelease then it's simply incremented (for example `4.0.0-rc.2` to `4.0.0-rc.3`).
+- A [semver-valid](https://semver.org/) version like 2.4.0.
+
+If the (resulting) version is greater than the current version then commits will be taken from the semver-latest tag until HEAD. I.e. documenting a new release before it's git-tagged. If the version matches an existing tag then a release will be inserted at the appriopriate place, populated with commits between that version's tag and the one before it. I.e. documenting a past release after it's git-tagged.
+
+Additional options for this command:
+
+- `--no-commits`: create an empty release.
+
+Works best on a linear git history. If `hallmark` encounters other tags in the commit range (which may happen if releases were made in parallel on other branches) it will stop there and not include further (older) commits.
+
+The `cc add` command also fixes markdown - both existing content and generated content. After you tweak the release following [Common Changelog](https://common-changelog.org) you may want to run `hallmark fix` again.
