Summary of the new feature / enhancement

As a user of PowerShell events, I often find myself frustrated with the ways Wait-Event works.

Primarily this concerns the Timeout being in seconds.

That may seem like a little thing, but it has a major downside: when I'm expecting events to be quick, this makes me wait a whole second I may not need to wait.

Additionally, based off of the way the command is written, the shortest possible wait is 1/5th of a second.

Proposed technical implementation details (optional)

Wait-Event should have a -Timespan parameter that takes a particular Timespan.

Most of the internal logic should remain the same, with the exception of modifying the "floor" value, which is currently 200ms.

The floor value should instead be one tenth of the timeout.
