API: Remove stuttering and consider error for options

[embano1]

Just out of my own experience using functional options (+1 on using them!) I recommend that you remove the Logger prefix in the options and add an error to the Option definition so you can handle invalid values, etc. without breaking the API at a later stage.

gopherlogs/options.go

Line 27 in c3745b1

func LoggerWithLogVerbosity(verbosity int) LoggerOptions {

Pushed e7212f4 which introduces returning errors to logger options and reformats logger options to drop the Logger* format:

l, err := gopherlogs.NewLogger(
    gopherlogs.WithLogLevel(0),
)
if err != nil {
    panic("New logger could not be created!")
}
