Description

**Is your feature request related to a problem? Please describe.**

Spinoff off https://github.com/lightninglabs/taproot-assets/issues/527. Sometimes we need a worker pool that doesn't cancel all workers when one errs. Right now we implement this by sometimes only logging errors from workers but not propagating them. Ideally we would propagate without cancelling any workers,

**Describe the solution you'd like**

Alternative to `fn.ParSlice` with the above behavior.

**Describe alternatives you've considered**

Research direction

Start by locating fn.ParSlice and tracing how it handles worker errors and cancellation. Define an alternative worker-pool path where errors are propagated without cancelling other workers, then add coverage showing workers continue after one returns an error.
