Summary of the PR

Change the name's type String to Cow<'static, str>. This allows the
library user to prevent string allocation from static strings, which is
how most crates use it.

This is an API breaking change.

Requirements

Before submitting your PR, please make sure you addressed the following
requirements:

  • All commits in this PR are signed (with git commit -s), and the commit
    message has max 60 characters for the summary and max 75 characters for each

    test.
  • All added/changed public-facing functionality has entries in the "Upcoming
    Release" section of CHANGELOG.md (if no such section exists, please create one).
  • Any newly added unsafe code is properly documented.

Change the name's type `String` to `Cow<'static, str>`. This allows the
library user to prevent string allocation from static strings, which is
how most crates use it.

This is an API breaking change.

Hm... This is the only use and requires ownership. So should we maybe just drop it from the daemon struct and make it part of the start_daemon function (as a String that can be moved through)?

Though, overall, I think this is a lot of code churn (for everyone using this) and additional complexity for very little gain.
