I would like to be able to determine the 'friendly' name of the log level from the numeric level

[trevor-vaughan]

Describe the feature

The default level is 3 but that isn't very user-friendly when trying to pass it back to users.

I would like to be able to lookup the 'friendly' name of the level from the current level setting.

At the moment, you could look up string name of log level by searching LogLevel constants:

import { LogLevels } from 'consola'

const [levelName, _] = Object.entries(LogLevels).find(([levelName, levelNum]) => levelNum === <certain_num>)

levelName // 'debug', for example

Exporting such a utility function from consola would be enhancement in terms of DX.

Thanks @NozomuIkuta. That's what I'm currently doing, it would just be nice to have a built-in, hence the feature request.

[NozomuIkuta]

I noticed that we have to take it into consideration that more than one keys (i.e. LogType) are associated with a number.

https://github.com/unjs/consola/blob/c2ff2b6d610b2442768ed01cd9aede21fff7fdb9/src/constants.ts#L6-L28

So, there seems to be no (easy) way a function can determine which LogType is actually meant by a number. 🤔

@NozomuIkuta Hmm...maybe return the 'most common' one?

For example, for 3 I would expect info with the others as aliases.
