Solid Queue 1.6.0 now supports fiber workers

A long-awaited feature thanks to @crmne on this release: instead of using a thread pool to run jobs in multiple threads per works, you can now use fibers on a single fiber reactor thread. To use this, you just need to specify the number of fibers instead of the number of threads in your worker configuration, like this:

workers:
  - queues: "api*"
    fibers: 100
    polling_interval: 0.05

It uses Async under the hood, so you need to have that as a dependency for it to work. Also, you need to be using fiber isolation in Rails (config.active_support.isolation_level`` = :fiber

).

This can be very useful for I/O-bound workloads, such as those involving LLM calls.
