log/slog: LevelTrace

[3052]

Proposal Details

would look like this, along with the current options:

const (
   LevelTrace Level = -8
   LevelDebug Level = -4
   LevelInfo  Level = 0
   LevelWarn  Level = 4
   LevelError Level = 8
)

its already referenced here:

https://godocs.io/log/slog#example-HandlerOptions-CustomLevels

and I think it would be a helpful addition.
