Handling of legacy CHANGELOG.md files

[DennisDobslaf]

I used this tool on a repo with an existing but old CHANGELOG.md file with no common schema.
This tool doesn't write to may legacy CHANGELOG.md on changelogger release but deletes the unreleased files.

Self-answering my question:

here is the reason: https://github.com/churchtools/changelogger/blob/master/app/Commands/ReleaseCommand.php#L103

As a workaround one can insert <!-- CHANGELOGGER --> at the top of a legacy CHANGELOG.md file.

Yes, the tool looks for <!-- CHANGELOGGER --> and uses this as placeholder. I will document this. Thx for pointing this out.
